drm/i915/display: sagv pre/post plane calls to check pmdemand support
For pmdemand cases, no need to even calculate the masks based
on the qgv points index. Though the current logic avoids setting
the registers based on the pmdemand support, some qgv point masks
are compared in vain and do nothing. So leave early if pmdemand
is supported.
