This adds dpm support for SI asics.  This includes:
- dynamic engine clock scaling
- dynamic memory clock scaling
- dynamic voltage scaling
- dynamic pcie gen1/gen2/gen3 switching
- power containment
- shader power scaling

Set radeon.dpm=1 to enable.

v2: enable hainan support, rebase
v3: guard acpi stuff
v4: fix 64 bit math
v5: fix 64 bit div harder
v6: fix thermal interrupt check noticed by Jerome
v7: attempt fix state enable

We weren't properly catching errors in dpm_enable()
and dpm_set_power_state().

Add a way to look up the bootup mvdd.  Required for DPM on SI.

Validate the voltages against the voltage requirements of the
dispclk.  We currently don't adjust the disp clock so it never
changes, but we need to filter out voltage levels that are too
low none the less.

Use the new fixed point functions for leakage
calculations on cayman.

This properly implemented dynamic state adjustment by
using a working copy of the requested and current
power states.
