This patch fixes a MES firmware boot failure issue
when backdoor loading the MES firmware.
MES firmware runtime DRAM size is changed to 512k,
the driver needs to reserve this amount of memory in
FB, otherwise adjacent memory will be overwritten by
the MES firmware startup code.

Adds a check in the map_hw_resources function to prevent a potential
buffer overflow. The function was accessing arrays using an index that
could potentially be greater than the size of the arrays, leading to a
buffer overflow.
Adds a check to ensure that the index is within the bounds of the
arrays. If the index is out of bounds, an error message is printed and
break it will continue execution with just ignoring extra data early to
prevent the buffer overflow.
Reported by smatch:

[Why]
Currently there is an error while translating input clock sates into
output clock states. The highest fclk setting from output sates is
being dropped because of this error.
[How]
For dcn35 and dcn351, make output_states equal to input states.

Fixes potential null pointer dereference warnings in the
dc_dmub_srv_cmd_list_queue_execute() and dc_dmub_srv_is_hw_pwr_up()
functions.
In both functions, the 'dc_dmub_srv' variable was being dereferenced
before it was checked for null. This could lead to a null pointer
dereference if 'dc_dmub_srv' is null. The fix is to check if
'dc_dmub_srv' is null before dereferencing it.
Thus moving the null checks for 'dc_dmub_srv' to the beginning of the
functions to ensure that 'dc_dmub_srv' is not null when it is
dereferenced.
Found by smatch & thus fixing the below:
drivers/gpu/drm/amd/amdgpu/../display/dc/dc_dmub_srv.c:133 dc_dmub_srv_cmd_list_queue_execute() warn: variable dereferenced before check 'dc_dmub_srv' (see line 128)

[Why]
Observe error message "Can't retrieve aconnector in hpd_rx_irq_offload_work"
when boot up with a mst tbt4 dock connected. After analyzing, there are few
parts needed to be adjusted:
1. hpd_rx_offload_wq[].aconnector is not initialzed before the dmub outbox
hpd_irq handler get registered which causes the error message.
2. registeration of hpd and hpd_rx_irq event for usb4 dp tunneling is not
aligned with legacy interface sequence
[How]
Put DMUB_NOTIFICATION_HPD and DMUB_NOTIFICATION_HPD_IRQ handler
registration into register_hpd_handlers() to align other interfaces and
get hpd_rx_offload_wq[].aconnector initialized earlier than that.
Leave DMUB_NOTIFICATION_AUX_REPLY registered as it was since we need that
while calling dc_link_detect(). USB4 connection status will be proactively
detected by dc_link_detect_connection_type() in amdgpu_dm_initialize_drm_device()

Convert open coded RMW accesses for LNKCTL2 to use
pcie_capability_clear_and_set_word() which makes its easier to
understand what the code tries to do.
LNKCTL2 is not really owned by any driver because it is a collection of
control bits that PCI core might need to touch. RMW accessors already
have support for proper locking for a selected set of registers
(LNKCTL2 is not yet among them but likely will be in the future) to
avoid losing concurrent updates.
