panfrost: Luminance-alpha AFBC unsupported on v7+

Browse source 
The L8_UNORM, A8_UNORM, and L8A8_UNORM v7 formats do not support AFBC,
regardless of swizzling. We're about to lift the restrictions on swizzling with
AFBC on v7, so we'll need to handle these cases explicitly to avoid using AFBC
in these cases.
