drm/{i915,xe}/fbdev: add intel_fbdev_fb_pitch_align()
For reasons still unknown, xe appears to require a stride alignment of
XE_PAGE_SIZE, and using 64 leads to sporadic failures. Go back to having
separate stride alignment for i915 and xe, until the issue is root
caused.
v2: Add FIXME comment, reference issue with Link (Ville)
