All indications seem to be that the version 0x30 table should be handled
the same way as 0x40 (as used on G80), at least for the parts that we
currently try use.

This commit cleans up the parsing to make it clearer about what we're
actually trying to achieve, and unifies the 0x30/0x40 parsing.

As opposed to repeatedly reading the amount back from the GPU every
time we need to know the VRAM size.

We should now fail to load gracefully on detecting no VRAM, rather than
something potentially messy happening.

Previously we were filling it the same as "placements", but in some

- Drop some more safe regs taht userspace shouldn't hit
- Constant base regs need relocs.  This allows us to use
constant buffers rather than the constant register file.
Also we don't want userspace to be able to set arbitrary
mc base values for the const caches.
- Track SQ_CONFIG so we know whether userspace is using
the cfile or constant buffers.
