Subject: [PATCH V3 3/5] accel/amdxdna: Enhance power management settings
Add SET_STATE ioctl to configure device power mode for aie2 device.
Three modes are supported initially.
POWER_MODE_DEFAULT: Enable clock gating and set DPM (Dynamic Power
Management) level to value which has been set by resource solver or
maximum DPM level the device supports.
POWER_MODE_HIGH: Enable clock gating and set DPM level to maximum DPM
level the device supports.
POWER_MODE_TURBO: Disable clock gating and set DPM level to maximum DPM
level the device supports.
Disabling clock gating means all clocks always run on full speed. And
the different clock frequency are used based on DPM level been set.
Initially, the driver set the power mode to default mode.
