drm/i915/adlp: Require always a power-of-two sized CCS surface stride
At the moment CCS FB strides must be power-of-two sized, but a follow-up change will add support remapping these FBs, allowing the FB passed in by userspace to have a non-POT sized stride. For these remapped FBs we can only remap the main surface, not the CCS surface. This means that userspace has to always generate the CCS surface aligning to the POT stride padded main surface (by setting up the CCS AUX pagetables accordingly). Adjust the CCS surface stride check to enforce this. No functional change. v2: - Fix the gen12_ccs_aux_stride() is not static sparse warning.
