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.

Currently just hooked up to the already-existing nouveau_hw, which should
handle all relevant chipsets as well as we currently can.
This will likely be eventually split out and improved into chipset specific
code at a later point.

This will make nouveau_pm attempt to report the card's current performance
level both during bootup, and through sysfs.
This is a very initial implementation, and can be improved a *lot*

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 rest of the connector code assumes we can kfree() the EDID pointer.
This causes things to blow up with the ACPI EDID pointer we get
passed.

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.

Instead of emptying the caches to avoid a race with the PFIFO puller,
go straight ahead and try to recover from it when it happens. Also,
kill pfifo->cache_flush and tile->lock, we don't need them anymore.

FW seems to be broken on nv18, it causes random lockups and breaks

This doesn't actually happen now, but there's a test case for an earlier
kernel where a GPU error is signalled on one of nv50's fake channels, and
the ramht lookup by the IRQ handler triggered an oops.
This adds a check for RAMHT's existance on a channel before looking up
an object handle.

On some boards the residual current DAC outputs can draw when they're
disconnected can be high enough to give a false load detection
positive (I've only seen it in the S-video luma output of some cards,
but just to be sure). The output line capacitance is limited and
sampling twice should fix it reliably.
