Subject: [PATCH 10/15] drm/vc4: plane: Omit pixel_order from the hvs_format
 for hvs5 only formats

From: Dave Stevenson <dave.stevenson@...pberrypi.com>

pixel_order is used for the earlier versions of the HVS, so is
redundant on the 10:10:10:2 and 10bit YUV formats that are only
supported on HVS5.
Remove the assignment from the table to avoid confusion.
