tests: Add prime_mmap_coherency for cache coherency tests

Browse Source 
Different than kms_mmap_write_crc that captures the coherency issues within the
scanout mapped buffer, this one is meant for test dma-buf mmap on !llc
platforms mostly and provoke coherency bugs so we know where we need the sync
ioctls.

I tested this with !llc and llc platforms, BTY and IVY respectively.
