[Why]
DM initializes VM context after DMCUB initialization.
This results in loss of DCN_VM_CONTEXT registers after z10.
[How]
Notify DMCUB when VM setup is complete, and have DMCUB

[WHY]
For DCN31 onward, LTTPR is to be enabled and set to Transparent by
VBIOS. Driver is to assume that VBIOS has done this without needing to
check the VBIOS interop bit.
[HOW]
Add LTTPR enable and interop VBIOS bits into dc->caps, and force-set the
interop bit to true for DCN31+.

[Why]
1. Driver use umachannelnumber to calculate watermarks for stutter.
In asymmetric memory config, the actual bandwidth is less than
dual-channel. The bandwidth should be the same as single-channel.
2. We found single rank dimm need additional delay time for stutter.

When driver re-enabled, OS will Set Mode YCbCr420 again,
which means the register RDPCS_PHY_DP_MPLLB_TX_CLK_DIV
should to be 1 again, but dmub fw can’t update the
register to 1 due to the mpll is not off
