We kept pointers to requested and current clock modes in every power state.
That was useless, more /global/ pointers in power struct are enough.

- only r4xx/r5xx/rs6xx/rs740 have clock gating atom table,
so disable it on r6xx.  it's already disabled on r7xx
- check to make sure the clock_gating hook exists before
calling it.  This avoids a segfault on asics without
that function.
- remove unused static power management function.

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

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
adds an LVDS pll quirk for a specific notebook.

Limiting the pll output range is a good thing generally as
it limits the number of possible pll combinations for a given
frequency presumably to the ones that work best on each card.
That's why the limits are in the bios tables. However, certain
duallink DVI monitors seem to like pll combinations that would
be limited by this at least on pre-DCE 3.0 r6xx hardware.  This
might need to be adjusted per family or per clock range in the
future.

This adds the r600 KMS + CS support to the Linux kernel.

The r600 TTM support is quite basic and still needs more
work esp around using interrupts, but the polled fencing
should work okay for now.

Also currently TTM is using memcpy to do VRAM moves,
the code is here to use a 3D blit to do this, but
isn't fully debugged yet.
