Allows *some* DP cards to keep working in some corner cases that most
people shouldn't hit.  I hit it all the time with development, so this
can stay for now.

On DP outputs we'll likely end up running vbios init tables here, which
may sleep.

This value interacts with some registers we don't currently know how to
program properly ourselves.  The default of 5 that we were using matches
what the VBIOS on early DP cards do, but later ones use 6, which would
cause nouveau to program an incorrect mode on these chips.

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
cases there're valid alternatives that we were ignoring completely.
Keeping a back-up memory type helps on several low-mem situations.

Fixes the !vbo_fifo path in the 3D driver on certain chipsets.  Still not
really any good idea of what exactly the magic achieves, but it makes
things work.

While we're at it, in the PCIEGART path, flush on unbinding also.

If we resume in a bad way, we'll get 0xffffffff in wptr, and then
oops with no console. This just adds a sanity check so that we can
avoid the oops and hopefully get more details out of people's systems.

This allows us to remove the internal bit algo bus used by
the radeon i2c algo.  We now register a radeon algo adapter
if the gpio line is hw capable and the hw inplementation is
available, otherwise we register a bit algo adapter.

- Add module option to force the display priority
  0 = auto, 1 = normal, 2 = high
- Default to high on r3xx/r4xx/rv515 chips
  Fixes flickering problems during heavy acceleration
  due to underflow to the display controllers
- Fill in minimal support for RS600

v2 - update display priority when bandwidth is updated
so the user can change the parameter at runtime and it
will take affect on the next modeset.

- 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.
