drm/nv40: implement ctxprog/state generation

Browse source 
The context programs are *very* simple compared to the ones used by
the binary driver.  There's notes in nv40_grctx.c explaining most of
the things we don't implement.  If we discover if/why any of it is
required further down the track, we'll handle it then.

The PGRAPH state generated for each chipset should match what NVIDIA
do almost exactly (there's a couple of exceptions).  If someone has
a lot of time on their hands, they could figure out the mapping of
object/method to PGRAPH register and demagic the initial state a little,
it's not terribly important however.

At time of commit, confirmed to be working at least well enough for
accelerated X (and where tested, for 3D apps) on NV40, NV43, NV44, NV46,
NV49, NV4A, NV4B and NV4E.

A module option has been added to force the use of external firmware
blobs if it becomes required.

/* NVIDIA context programs handle a number of other conditions which are
* not implemented in our versions. It's not clear why NVIDIA context
* programs have this code, nor whether it's strictly necessary for
* correct operation. We'll implement additional handling if/when we
* discover it's necessary.
*
* - On context save, NVIDIA set 0x400314 bit 0 to 1 if the "3D state"
* flag is set, this gets saved into the context.
* - On context save, the context program for all cards load nsource
* into a flag register and check for ILLEGAL_MTHD. If it's set,
* opcode 0x60000d is called before resuming normal operation.
* - Some context programs check more conditions than the above. NV44
* checks: ((nsource & 0x0857) || (0x400718 & 0x0100) || (intr & 0x0001))
* and calls 0x60000d before resuming normal operation.
* - At the very beginning of NVIDIA's context programs, flag 9 is checked
* and if true 0x800001 is called with count=0, pos=0, the flag is cleared
* and then the ctxprog is aborted. It looks like a complicated NOP,
* its purpose is unknown.
* - In the section of code that loads the per-vs state, NVIDIA check
* flag 10. If it's set, they only transfer the small 0x300 byte block
* of state + the state for a single vs as opposed to the state for
* all vs units. It doesn't seem likely that it'll occur in normal
* operation, especially seeing as it appears NVIDIA may have screwed
* up the ctxprogs for some cards and have an invalid instruction
* rather than a cp_lsr(ctx, dwords_for_1_vs_unit) instruction.
* - There's a number of places where context offset 0 (where we place
* the PRAMIN offset of the context) is loaded into either 0x408000,
* 0x408004 or 0x408008. Not sure what's up there either.
* - The ctxprogs for some cards save 0x400a00 again during the cleanup
* path for auto-loadctx.
