There is no "chunknown" structure; that part of the union is an artefact
from falsely believing vertex/tiler MFBDs could have render targets
attached (they can't). These are just plain old AFBC fields, and if
there is no AFBC, it's error to set these field.

pan/decode: Do not print uniform/buffers explicitly

For our purposes of driver debugging, the contents of uniform buffers
are rarely interesting; we're more concerned about the metadata setting
them up.

We do need to be careful to validate the sizes of both uniforms and
uniform buffers.

pan/decode: Add static bounds checking utility

Many structures in the command stream have a GPU address and size
determined statically. We should check that the pointers we are passed
are valid and the buffers they point to are big enough for the given
size. If they're not, an MMU fault would be raised.

panfrost: Correct polygon size computations

While the algorithm for computing the header size has been correct for a
while, we used a major hack to conservatively guess the body size. Let's
scrap that and figure out the algorithm we actually need to use to be
bit-identical with what the hardware expects.

We do have to be careful to add the header size to total comptued BO
size.

It's not clear how big the polygon list needs to be in practice -- but
it has to be somewhat bigger than the polygon list itself. This needs
more investigation. If we size the polygon list exactly based on the
polygon_list_size field, we get faults like:

[ 1224.219886] panfrost ff9a0000.gpu: Unhandled Page fault in AS0 at VA 0x000000001BDE8000

pan/decode: Verify and omit polygon size

The polygon sizes are computed from the width/height/flags, so we can

computation algorithms are bit-identical. If they are, we can omit the
computed fields.
