drm/amdgpu: Add sysfs interfaces for NPS mode
Add a sysfs interface to see available NPS modes to switch to -
cat /sys/bus/pci/devices/../available_memory_paritition
Make the current_memory_partition sysfs node read/write for requesting a
new NPS mode. The request is only cached and at a later point a driver
unload/reload is required to switch to the new NPS mode.
Ex:
echo NPS1 > /sys/bus/pci/devices/../current_memory_paritition
echo NPS4 > /sys/bus/pci/devices/../current_memory_paritition
The above interfaces will be available only if the SOC supports more than
one NPS mode.
Also modify the current memory partition sysfs logic to be more
generic.
