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.

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.

The GPIO_I2C_INFO table does not always have
ATOM_MAX_SUPPORTED_DEVICE entries. Limit
the number of indices to the size of the
table.
Should fix Novell bug 589022.

Some GPUs have an APM/ACPI PM mode selection switch and some BIOSes
set this to APM. We really want this in ACPI mode for Linux.

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.
