Currently, the driver is only waiting for 1ms for
idle patterns. But starting from LNL and beyond,
the MST wants the driver to wait for 1640us before
timing out (which we round up to 2ms).
v1: Introduced the 2ms wait timeout.
v2: Segregated the wait timeout for platforms before & after LNL.

Link Off Between Active Frames, is a new feature for eDP
that allows the panel to go to lower power state after
transmission of data. This is a feature on top of ALPM, AS SDP.
Add compute config during atomic-check phase.

Link Off Between Active Frames (LOBF) allows an eDP link to be turned Off and On
durning long VBLANK durations without enabling any of the PSR/PSR2/PR modes of
operation.
Bspec: 71477
Note: This is a feature has dependency on ALPM, AS SDP. So the below changes
are done on top of the following
