[PATCH v5 04/10] platform/raspberrypi: vchiq-mmal: Support ISP parameters and stats

[Jai Luthra <jai.luthra@ideasonboard.com>]

The ISP used on BCM2835 and derivative platforms is behind the VCHIQ
bus, where some parameters and statistics are accessed through the MMAL
layer.

So add the relevant structures, macros and enum values.
