drm/xe: Stop checking for power_lost on D3Cold

Browse source

GuC reset status is not reliable for this purpose and it is
once in a while ending up in a situation of D3Cold, where
power_reset is false and without the proper memory restoration
the GuC reload and Display will fail to come back from D3Cold.

So, let's do a full restoration of everything if we have a risk
of losing power, without further optimizations.

v2: also remove the gut_in_reset function (Anshuman)
