The idea is to flag a power state with a certain type and use
that type to decide on what state to select.  On r6xx+, we
select a state and then transition between clock modes in that
state.  On pre-r6xx, we transition between states directly.

The general idea is to validate the current hw state
against the set of power states and select a power
state based on that.  This patch just pulls the power
states from the bios and prints the information.  It
is not currently hooked up in the actual power management
code.  Hooking it up will require reworking the the current
power state selection code and will be handled in a future
patch.

Additionally, we'd need to decide on some default lower
power states for cards without power tables.

v2 - increment state_index after checking for default state
v3 - fix typo in pm init on pre-atom cards, handle pre-atom
cards without x86 bioses

Only flush the gpu caches before we submit a fence.
This leads to a small performance boost when we take
the extra gpu cache flushes out of the ddx and mesa.
Once this patch is in and the drm version is bumped,
we can remove the flushes from the ddx and drm.

Also, remove the extra cache flushes from the blit
routine.

Rework the pll algo selection so that the pll algo
in use can be selected more easily.  This allows
us to select different pll divider selection algos
for specific monitors that work better with one algo
or the other.  This is needed for the next patch which

In suspend path we unmap the GART table while in cleaning up
path we will unbind buffer and thus try to write to unmapped
GART leading to oops. In order to avoid this we don't call the
suspend path in cleanup path. Cleanup path is clever enough
to desactive GPU like the suspend path is doing, thus this was
redondant.
