panfrost: Switch formats to table

Rather than heuristically guessing what PIPE formats correspond to what
in the hardware, hardcode a table. This is more verbose, but a lot more
obvious -- the previous format support code was a source of endless
silent bugs.

v2: Don't report RGB233 (icecream95). Allow RGB5 for texturing
(icecream95).
