drm/msm/dpu: use standard functions in _dpu_format_populate_plane_sizes_ubwc()

The _dpu_format_populate_plane_sizes_ubwc() used MSM_MEDIA_ALIGN() and
MSM_MEDIA_ROUNDUP(), macros inherited from the previous implementation,
msm_media_info.h. Replace them with the standard Linux macros,
round_up() and DIV_ROUND_UP() respectively.
