drm/i915/psr: CAN_PSR() macro to check for PSR source and sink support.
The global variable dev_priv->psr.sink_support is set if an eDP sink
supports PSR. Use this instead of redoing the check with is_edp_psr().
Combine source and sink support checks into a macro that can be used to
return early from psr_{invalidate, single_frame_update, flush}.
