On certain boards, there's BIOS scripts and memory timings that need to
be modified with the memclk.  Just pass in the entire perflvl struct and
let the chipset-specific code decide what to do.

This isn't correct everywhere yet, but since we don't use the data yet
it's perfectly safe to push in, and the information we gain from logs
will help to fix the remaining issues.

- fixed up formatting
- free parsed timing info on takedown
- switched timing table printout to debug loglevel

nouveau_bios_fp_mode() zeroes the mode struct before filling in relevant
entries.  This nukes the mode id initialised by drm_mode_create(), and
causes warnings from idr when we try to remove the mode.

Used on nv17-nv28, they contain memory clocks and timings, only one of
the table entries can actually be used, depending on the RAMCFG
straps, and it's usually higher than the frequency programmed on boot
by the BIOS.

The memory timings listed in table version 0x1x are used to init the
0x12xx range but they aren't required for reclocking to work.

    drm/nouveau: support fetching LVDS EDID from ACPI

    Based on a patch from Matthew Garrett.

It doesn't seem to revert cleanly, but the problem lies in these
two config entries:

CONFIG_ACPI=y
CONFIG_ACPI_VIDEO=m

Adding a select for ACPI_VIDEO appears to be the best solution, and
is comparable to what is done in DRM_I915.  Builds, boots, and appears to
work correctly.

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 most important part of this change is that we now instruct PFIFO to
drop all pending fetches, rather than attempting to skip a single dword
and hope that things would magically sort themselves out - they usually
don't, and we end up with PFIFO being completely hung.

This commit also adds somewhat more useful logging when these exceptions
occur.
