This turns previously global functions into static, thus removing
compile-time warnings such as:
warning: no previous prototype for 'get_highest_allowed_voltage_level'
[-Wmissing-prototypes]

102 | int rv1_vbios_smu_send_msg_with_param(struct clk_mgr_internal *clk_mgr, unsigned int msg_id, unsigned int param)

Changes since v1:
- As suggested by Rodrigo Siqueira:
1. Rewrite function signatures to make them more readable.
2. Get rid of unused functions in order to remove 'defined but not
used' warnings.

Use the struct display_mode_lib pointer instead of passing lots of large
arrays as parameters by value.
Addresses this warning (resulting in failure to build a RHEL debug kernel
with Werror enabled):
../drivers/gpu/drm/amd/amdgpu/../display/dc/dml/dcn31/display_mode_vba_31.c: In function ‘UseMinimumDCFCLK’:

NOTE: AFAICT this function previously had no observable effect, since it
only modified parameters passed by value and doesn't return anything.
Now it may modify some values in struct display_mode_lib passed in by
reference.

Move code using the Pipe struct to a new helper function.
Works around[0] this warning (resulting in failure to build a RHEL debug
kernel with Werror enabled):
../drivers/gpu/drm/amd/amdgpu/../display/dc/dml/dcn31/display_mode_vba_31.c: In function ‘dml31_ModeSupportAndSystemConfigurationFull’:

The culprit seems to be the Pipe struct, so pull the relevant block out
into its own sub-function. (This is porting
commit a62427ef9b ("drm/amd/display: Reduce stack size for dml21_ModeSupportAndSystemConfigurationFull")
from dml31 to dml21)
[0] AFAICT this doesn't actually reduce the total amount of stack which
can be used, just moves some of it from
dml31_ModeSupportAndSystemConfigurationFull to the new helper function,
so the former happens to no longer exceed the limit for a single
function.

Once EDID is parsed, the monitor HDMI support information is available

drm_detect_hdmi_monitor() to retrieve the same information, which
is less efficient. Change to drm_display_info.is_hdmi

[Why]
During dcn31_stream_encoder_create, if PHYC/D get remapped to F/G on B0
then we'll index 5 or 6 into a array of length 5 - leading to an
access violation on some configs during device creation.
[How]
Software won't be touching PHYF/PHYG directly, so just extend the
array to cover all possible engine IDs.
Even if it does by try to access one of these registers by accident
the offset will be 0 and we'll get a warning during the access.

[Why]
When HPD IRQ occurs, it triggers a PSR disable and reenable
directly through dc layer.
Since it does not pass through the power layer, the layer
that tracks whether PSR is enabled or disabled and which
masks are set, this layer is now out of sync with the real
PSR state in FW.
Theoretically PSR can be enabled during hw programming
sequences or any other situation where we must disable PSR.
[How]
Check if PSR is enabled before doing PSR disable/reenable.
