panfrost: Support linear depth textures 

This combination has not yet been seen "in the wild" in traces, but to
support linear depth FBOs, ~bruteforce reveals this bit pattern is
necessary. It's not yet clear why the meanings of 0x1 and 0x2 are
essentially flipped (tiled vs linear for colour, linear vs some sort of
tiled for depth).
