Subject: [PATCH 12/13] platform/raspberrypi: vchiq-mmal: Add defines for
 mmal_es_format flags

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

There is a flags field in struct mmal_es_format, but the defines
for what the bits meant weren't included in the headers.
For V4L2_PIX_FMT_NV12_COL128 support we need them, so add them in.
