drm/amd/display: Set number of pipes to 1 if the second pipe was disabled
[why]
Some ODM-related register settings are inconsistently updated by VBIOS, causing
the state in DC to be invalid, which would then end up crashing in certain
use-cases (such as disable/enable device).
[how]
Check the enabled status of the second pipe when determining the number of
OPTC sources. If the second pipe is disabled, set the number of sources to 1
regardless of other settings (that may not be updated correctly).
