drm/msm: fix allocation of dumb buffers for non-RGB formats

Browse source

Several users (including IGT kms_getfb tests) allocate DUMB buffers for
YUV data. Commit 538fa012cb ("drm/msm: Compute dumb-buffer sizes with
drm_mode_size_dumb()") broke that usecase, since in those cases
drm_driver_color_mode_format() returns DRM_FORMAT_INVALID.

Handle the YUV usecase, aligning to 32-bit pixels.
