MTL supports FP16 format which is a binary floating-point computer
number format that occupies 16 bits in computer memory. In this test
platform shall render compression in display engine to receive
FP16 compressed formats.

This was tested with kernel patch,
https://patchwork.freedesktop.org/patch/563854
