Because we aren't in a suspend state the poll will still run when we have switcherooed a card off.

I blame Hi-5 or the Wiggles for lowering my IQ, move the fix inside some

At least 'make CONFIG_DEBUG_SECTION_MISMATCH=y' causes
drivers/gpu/drm/radeon/atombios_crtc.c: In function 'atombios_crtc_set_pll':
drivers/gpu/drm/radeon/atombios_crtc.c:684: warning: 'pll' may be used uninitialized in this function
which has the looks of a falso positive.
Add a default: case so that gcc rests assured that all possible pll_id's are covered.
Keep the present cases that fall through to the default one for self-documentation.

list reservation was too optimistic about ttm object reservation
and could think that an object reserved by some other process
as reserved by the list reservation which was false. Thus when
unreserving the list it might unreserve object that it didn't
reserved in the list. Sorry if it's hard to follow but this
kind of things are just causing headheck.

This patch is a combination of the previous two profile
patches, but without the index bugs. It cleans up and
fixes some issues with pm profile setup on r6xx chips.
Some tables have different orderings for the power states,
also, r600 only has 1 clock mode per power state. On
desktop cards there are no battery modes, so the low and high
power states are the same. For the low profile case, choose
the lower clock mode.

- Separate dynpm and profile based power management methods. You can select the pm method
by echoing the selected method ("dynpm" or "profile") to power_method in sysfs.
- Expose basic 4 profile in profile method
"default" - default clocks
"auto" - select between low and high based on ac/dc state
"low" - DC, low power mode
"high" - AC, performance mode
The current base profile is "default", but it should switched to "auto" once we've tested
on more systems. Switching the state is a matter of echoing the requested profile to
power_profile in sysfs. The lowest power states are selected automatically when dpms turns
the monitors off in all states but default.
- Remove dynamic fence-based reclocking for the moment. We can revisit this later once we
have basic pm in.
- Move pm init/fini to modesetting path. pm is tightly coupled with display state. Make sure
display side is initialized before pm.
- Add pm suspend/resume functions to make sure pm state is properly reinitialized on resume.
- Remove dynpm module option. It's now selectable via sysfs.

Add two new sysfs attributes:
- dynpm
- power_state
Echoing 0/1 to dynpm disables/enables dynamic power management.
The driver scales the sclk dynamically based on the number of
queued fences. dynpm only scales sclk dynamically in single head
mode.
Echoing x.y to power_state selects a static power state (x) and clock
mode (y). This allows you to statically select a power state and clock
mode. Selecting a static clock mode will disable dynpm.

- pm_prepare() - disables crtc mem requests right now.

This also simplifies the code and enables reclocking with multiple heads
active by tracking whether the power states are single or multi-head
capable.
