We should definitely stick to the midgard bindings here and add all the compatibles
even if we haven't tested yet, maybe by adding a warning mechanism reporting
when used on an untested mali core ?

BTW rob, I resent the bifrost binding doc with an unique, "arm,mali-bifrost"
compatible, adding it would help starting debugging bifrost aswell !
