drm/i915/psr: enable psr2 for y cordinate panels

Browse Source 
Psr2 is enabled only for y cordinate panels.Once GTC (global time code)
is implemented,this restriction is removed so that psr2
can work on panels without y cordinate support.

v2: (Rodrigo)
- Move the check to intel_psr_match_conditions

v3: (Rodrigo)
- add return false

v4: rebase
