kmssink: Add support for mxsfb-drm driver

The mxsfb-drm driver has been added to the kernel long ago and will now
be the default display driver for NXP i.MX28, i.MX6SX and i.MX7D
processors so now is a good time to add it to kmssink.

Also, this is used in the upcoming i.MX8MQ and i.MX8MM processors.
