Reinstate the mmap ioctl for all current integrated platforms.
The intention was really to have it disabled for discrete graphics

I already pushed v2 of this last week with the following amended:
"This was reported to break ADL-P with the media stack, which was not
the intention. Although longer term we do still plan to sunset this
ioctl even for integrated, in favour of using mmap_offset instead."
Ah, OK.
Thanks.
