drm/xe/vram: report FLAT_CCS base misalignment

Browse source

So we can easily check if a machine had the CCS bug, when looking back
over bug reports where we have the same machine with newer kernel.

Example print for a machine with the CCS bug:

  FLAT_CCS base:27bbff800, aligned:no

v2 (Matt B):
  - Unconditionally print the base + alignment
