drm/msm: convert all pixel format logging to use %p4cc

Browse source

Logging u32 pixel formats using %4.4s format string with a pointer to
the u32 is somewhat questionable, as well as dependent on byte
order. There's a kernel extension format specifier %p4cc to format 4cc
codes. Use it across the board in msm for pixel format logging.

This should also fix the reported build warning:

  include/drm/drm_print.h:536:35: warning: '%4.4s' directive argument is
  null [-Wformat-overflow=]
