If BIOS enables/disables C6, i915 should do the same. Also, retain
this value across driver reloads. This is needed only for MTL as
of now due to an existing bug in OA which needs C6 disabled for
it to function. BIOS behavior is also different across platforms
in terms of how C6 is enabled.
v2: Review comments (Umesh)
v3: Cache the C6 enable value for all MTL. The OA WA is needed only
for A/B step, but we don't need to check for that here.
v4: Rename to mtl_check_bios_c6_setup()

This one's already pushed with the MTL OA series.
