5dbfcd25a0 drm/amd/display: fix cursor offset on rotation 180
Cursor gets clipped off in the middle of the screen with hw rotation
180. Fix a miscalculation of cursor offset when it's placed near the
edges in the pipe split case.

Cursor bugs with hw rotation were reported on AMD issue tracker:
https://gitlab.freedesktop.org/drm/amd/-/issues/2247

The issues on rotation 270 was fixed by:
https://lore.kernel.org/amd-gfx/20221118125935.4013669-22-Brian.Chang@amd.com/
that partially addressed the rotation 180 too. So, this patch is the
final bits for rotation 180.

54618888d1 drm/amd/display: break down dc_link.c
[why]
dc_link contains over 30k line of code, the decision is to break it
down to files residing in link folder based on functionality. This
change is the last break down change which will remove dc_link.c
file after everything is broken down.

[how]
Move remaining dc_link.c functions into link_detection, link_dpms,
link_validation, link_resource, and link_fpga and remove dc_link.

5842abd985 drm/amd/display: Use the largest vready_offset in pipe group
[WHY]
Corruption can occur in LB if vready_offset is not large enough.
DML calculates vready_offset for each pipe, but we currently select the
top pipe's vready_offset, which is not necessarily enough for all pipes
in the group.

[HOW]
Wherever program_global_sync is currently called, iterate through the
entire pipe group and find the highest vready_offset.

64a9f19a5a drm/amd/display: move remaining FPU code to dml folder
In the process of enabling DCN support for arm64, I found that the
dcn10_resource_construct_fp function in dcn10/dcn10_resource.c still
needs to use FPU. This will cause compilation to fail on ARM64 platforms
because -mgeneral-regs-only is enabled by default to disable the
hardware FPU. So move dcn10_resource_construct_fp from dcn10 folder to
dml/dcn10 folder to enable hardware FPU for that function.

9c75891fee drm/amd/display: rework recent update PHY state commit
[why]
Original change 594b237b9a ("drm/amd/display: Add
interface to track PHY state") was implemented by assuming stream's
dpms off is equivalent to PHY power off.
This assumption doesn't hold in following situations:
1. MST multiple stream scenario, where multiple streams are sharing the
same PHY output. Toggle dpms off for one of the stream doesn't power
off the PHY due to the presence of other streams.
2. enable stream failure scenario, where enable stream fails due to
failure of link training. This will cause DPMS off is set to false, while
the actual PHY power state is off in certain cases.
Due to the problematic assumption, the logic will skip disabling
other streams for MST multiple stream scenario, therefore PHY is
not actually powered off.

[how]
1. Rework this refactor by moving PHY state update down to hardware
level, where we update PHY state in place when hardware sequencer
is actually changing the power state of the PHY hardware.
2. Reimplement symclk on TX off workaround in place when we are actually
calling transmitter control to power off PHY in dcn32. Note the workaround is
added due to the lack of proper software interface to set TX while keeping
symclk on. We plan to address this interface problem so we can set TX off
only without affecting symclk in future dcn versions.

[Why]
enable_sw_cntl_psr flag is not needed.
For PSR1 and PSR2, we should be passing

[How]
Remove enable_sw_cntl_psr flag from driver.

4e65878de0 drm/amd/display: Cursor lag with PSR1 eDP
[Why]
On edp with psr1, we do not provide updates
of the cursor position regularly to firmware
like with PSR2. To send updates regularly,
the flag enable_sw_cntl_psr has to equal 1,
but cursor update should be provided
regularly to FW regardless of that flag.

[How]
Ensure that we always send cursor updates to
firmware when PSR version equals 1.
