Following to "drm/nv50/pm: s/unk05/vdec/", let's rename the PLL to PLL_VDEC
PLL names are purely indicative and are based on the most important engine
it clocks.

Should fix issues with kexec, and as a nice side bonus, the code to avoid
having PDISP disappear will also fix hibernate on those effected systems.

This has the effect of ensuring the encoders which were active before we
loaded get disconnected properly before we start reprogramming them.
Also removing a bit of cargo-cult from the initial evo pushbuf.

Otherwice code that responsible for idling the card can't work.
BIOS init tables are supposed to init the clocks to correct values,
so that shouldn't cause any problems (we don't reclock by default anyway)

Exposes the same connector properties as the Radeon implementation, however
their behaviour isn't exactly the same. The primary difference being that
unless both hborder/vborder have been defined by the user, the driver will
keep the aspect ratio of the overscanned area the same as the mode the
display is programmed for.
Enabled for digital outputs on GeForce 8 and up, excluding GF119.

A NV49 appeared a while back that was using the "nv41 style" pwm registers,
rather than the "nv40 style" ones my board is using. This disproves the
previous theory that the pwm controller choice is chipset-specific.
So, after looking at a bunch of vbios images it appears that the next viable
theory is that we should select the pwm controller to use based on the gpio
line the fan is tied to, just like we do on nv50.

The handling of the internal pwm fan controller is similar enough between
current chipsets that it makes sense to share the logic, and bugfixes :)
No hw backends converted yet, will automatically fall-through to the
"old" per-chipset fanspeed hooks for now.

Exposes the following sysfs entries:
- fan0_input: read the rotational speed of the fan (poll a bit during 250ms)
- pwm0: set the pwm duty cycle
- pwm0_min/max: set the minimum/maximum pwm value
v2 (Ben Skeggs):
- nv50 pwm controller code removed in favour of other more complete code
- FAN_RPM -> FAN_SENSE
- merged FAN_SENSE readout into common code, not at all nv50-specific
- protected fanspeed changes with perflvl_wr
- formatting tidying
- added some comments where things are shaky
v3 (Martin Peres)
- ensure duty min/max from thermal table are sane

Otherwise each driver would need to keep the information inside
their own framebuffer object structure. Also add offsets[]. BOs
on the other hand are driver specific, so those can be kept in
driver specific structures.

Previously we were calling back move_notify in error path when the
bo is returned to it's original position or when destroy the bo.
When destroying the bo set the new mem placement as NULL when calling
back in the driver.
Updating nouveau to deal with NULL placement properly.
v2: reserve the object before calling move_notify in bo destroy path
at that point ttm should be the only piece of code interacting
with the object so atomic_set is safe here.
v3: callback move notify only once the bo is in its new position
call move notify want swaping out the buffer
v4:- don't call move_notify when swapin out bo, assume driver should
do what is appropriate in swap notify
- move move_notify call back to ttm_bo_cleanup_memtype_use for
destroy path

Provide helper function to compute the kernel memory size needed
for each buffer object. Move all the accounting inside ttm, simplifying
driver and avoiding code duplication accross them.

would have run into the issue since a longtime but it seems
ghost object are rare when you have plenty of vram ;)

If the card is capable of more than 32-bit, then use the default
TTM page pool code which allocates from anywhere in the memory.
Note: If the 'ttm.no_dma' parameter is set, the override is ignored
and the default TTM pool is used.
V2 use pci_set_consistent_dma_mask
