drm/radeon/kms/pm: rework power management
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.
