[Why]
There can be some unsynchronized frames when entering/exiting
LFC. This may cause tearing or stuttering at such transitions.
[How]
Add a enter/exit margin to algorithm to smoothly transition into
and out of LFC without desynchronizing frames.

* Improve freesync low frame rate compensation (frame doubling) behavior
* Update ABM parameters, limit minimum adjustment

Previously 8k30 worked with dsc and odm combine due to a workaround that ran
the formula a second time with dsc support enable should dsc validation fail.
This worked when clocks were low enough for formula to enable odm to lower
voltage, however now broke due to increase
From: Wesley Chalmers
[WHY]
Presently, there is no way for clocks to be lowered, only raised.
[HOW]
Compare clock status against previous known clock status, and optimize
if different.
This requires re-ordering the layout of the dc_clocks structure, as the
current ordering allows identical clock
From: Zhan Liu
[Why]
When more than 2 displays are connected to the graphics card,
only the minimum memory clock is needed. However, when more
displays are connected, the minimum memory clock is not
sufficient enough to support the overwhelming bandwidth.
System will hang under this circumstance.

[Why]
Separating the hardware initialization from the creation of the
dc structures gives greater flexibility to the dm to override
options for debugging.
[How]
Move the hardware initialization call to a new function,
dc_hardware_init. No functional change is intended.

From: Wesley Chalmers
[WHY]
This change was made because DTO programming was double-buffered, which
is itself an issue. After deactivating the DTO double buffer, this
change becomes unnecessary.
