This replaces all the pll_types definitions for ones that match the types
used in the tables in recent VBIOS versions.

get_pll_limits() will now accept either type or register value as input
across all limits table versions, and will store the actual register ID
that a PLL type refers to in the returned structure.

The TMDS output of an nv11 was being detected as LVDS, because it uses

sil164 and friends are the most common, usually they just need to be
poked once because a fixed configuration is enough for any modes and
clocks, so they worked without this patch if the BIOS had done a good
job on POST. Display couldn't survive a suspend/resume cycle though.
Unfortunately, BIOS scripts are useless here.

Init-compute-mem was the last piece missing for nv0x-nv3x card
cold-booting. This implementation is somewhat lacking but it's been
reported to work on most chipsets it was tested in. Let me know if it
breaks suspend to RAM for you.

There's a report of this quirk breaking modesetting on at least one board.
After discussion with Francisco Jerez, we've decided to remove it:

<darktama> it's not worth limiting the quirk to just where we know it can
           work?  i'm happy either way really :)
<curro> hmm, don't think so, most if not all DCB15 cards have just one DAC
<curro> and with that quirk there's no way to tell if the load comes from
        the VGA or DVI port

On nv50 it became impossible to attempt a PCI ROM shadow of the VBIOS,
which will break some setups.

This patch also removes the different ordering of shadow methods for
pre-nv50 chipsets.  The reason for the different ordering was paranoia,
but it should hopefully be OK to try shadowing PRAMIN first.
