This feature synchronizes multiple displays with various timings
to a display with the highest refresh rate
it is enabled if edid caps flag multi_display_sync is set to one

There are limitations on refresh rates allowed
that can be synchronized. That would
prevent from underflow and other potential
corruptions.

Multi display synchronization is using the
same functions as timing_sync in order to minimize
redunduncy and decision to disable synchronization is
based on trigger parametre set in DM

Feature is developed for DCN1 and DCE11

Update the programming sequence to allow DMCU firmware to be loaded by
PSP. This code detects whether the firmware is loaded and does a check
to verify the expected interface version and checks for correct response
from micro controller.

Added registry key method to allow force loading of firmware from kernel
mode driver for test purposes. This is old method of firmware loading
without PSP.

Moved some init sequences into dc/dmcu.

Changed loading sequence to initialize IRAM after firmware completely
loaded. Firmware will now disable features that use IRAM
until initialized.

Currently in the case where some of the allocations fail for dce110_tgv,
dce110_xfmv, dce110_miv or dce110_oppv then the exit return path ends
up leaking allocated objects. Fix this by kfree'ing them before returning.
Also re-work the comparison of the null pointers to use the !ptr idiom.
