[Why]
The amdgpu_dm file contains most of the code that works as an interface
between DRM API and DC. As a result, this file becomes very large since
it comprises multiple abstractions such as plane manipulation.
[How]
This commit extracts the plane code to its specific file named
amdgpu_dm_plane. This change does not change anything inside the
functions; the only exception is converting some static functions to a
global function.

[Why & How]
In order to leverage igt tool to maintain mst feature, expose new
debugfs entry "mst_progress_status".
In our dm flow, record down the result of each phase of mst and user
can examine the mst result by checking whether each phase get completed
successfully.

[Why & How]
Add "is_mst_connector" debugfs entry to help distinguish whether
a connector is in a mst topology or not.
Access it with the following command:
cat /sys/kernel/debug/dri/0/DP-X/is_mst_connector
Result:
- "root" stands for the root connector of the topology
- "branch" stands for branch device of the topology
- "end" stands for leaf node connector of the topology
- "no" stands for the connector is not a device of a mst topology

[Why & How]
Correct few problems below to have debugfs trigger_hotplug entry
supports mst case
* Adjust the place for acquiring the hpd_lock. We'll also access
dc_link when simulate unplug
* When detect the connector is a mst root, call
reset_cur_dp_mst_topology() to simulate unplug
* Don't support hotplug caused by CSN message since we can't change
mst topology info directly. We can't simulate that
* Clean up redundant code

[Why]
When CONFIG_DRM_AMD_SECURE_DISPLAY is enabled, it will try
to register vertical interrupt 0 for specific task.
Currently, only dcn10 have defined relevant info for vertical interrupt
0. If we enable CONFIG_DRM_AMD_SECURE_DISPLAY for other dcn ASIC, will
get DC_IRQ_SOURCE_INVALID while calling dc_interrupt_to_irq_source() and
cause pointer errors.
[How]
Add support of vertical interrupt 0 for all dcn ASIC.

TTM used to track the "acc_size" of all BOs internally. We needed to
keep track of it in our memory reservation to avoid TTM running out
of memory in its own accounting. However, that "acc_size" accounting
has since been removed from TTM. Therefore we don't really need to
track it any more.

Some userspace presumes that the first connected connector is the main
display, where it's supposed to display e.g. the login screen. For
laptops, this should be the main panel.
This patch call drm_helper_move_panel_connectors_to_head() after
drm_bridge_connector_init() to make sure eDP stay at head of
connected connector list. This fixes unexpected corruption happen
at eDP panel if eDP is not placed at head of connected connector
list.
Changes in v2:
-- move drm_helper_move_panel_connectors_to_head() to
dpu_kms_drm_obj_init()
Changes in v4:
-- move drm_helper_move_panel_connectors_to_head() to msm_drm_init()

This patch re-introduces support for GuC v69 in parallel to v70. As this
is a quick fix, v69 has been re-introduced as the single "fallback" guc
version in case v70 is not available on disk and only for platforms that
are out of force_probe and require the GuC by default. All v69 specific
code has been labeled as such for easy identification, and the same was
done for all v70 functions for which there is a separate v69 version,
to avoid accidentally calling the wrong version via the unlabeled name.
When the fallback mode kicks in, a drm_notice message is printed in
dmesg to inform the user of the required update. The existing
logging of the fetch function has also been updated so that we no
longer complain immediately if we can't find a fw and we only throw an
error if the fetch of both the base and fallback blobs fails.
The plan is to follow this up with a more complex rework to allow for
multiple different GuC versions to be supported at the same time.
v2: reduce the fallback to platform that require it, switch to
firmware_request_nowarn(), improve logs.

DRM formats are defined to be little-endian, unless the
DRM_FORMAT_BIG_ENDIAN flag is set. Hence when converting from one
format to another, multi-byte pixel values loaded from memory must be
converted from little-endian to host-endian. Conversely, multi-byte
pixel values written to memory must be converted from host-endian to
little-endian. Currently only drm_fb_xrgb8888_to_rgb332_line() includes
endianness handling.
Fix gud_xrgb8888_to_color() on big-endian platforms by adding the
missing endianness handling.

DRM API requires the DRM's driver to be backed with the device that can
be used for generic DMA operations. The VirtIO-GPU device can't perform
DMA operations if it uses PCI transport because PCI device driver creates
a virtual VirtIO-GPU device that isn't associated with the PCI. Use PCI's
GPU device for the DRM's device instead of the VirtIO-GPU device and drop
DMA-related hacks from the VirtIO-GPU driver.

Change the order of SHMEM initialization and reservation locking
to make code cleaner and to prepare for transitioning of the common
GEM SHMEM code to use the GEM's reservation lock instead of the
shmem.page_lock.
There is no need to lock reservation during allocation of the SHMEM pages
because the lock is needed only to avoid racing with the async host-side
allocation. Hence we can safely move the SHMEM initialization out of the
reservation lock.
