accel/amdxdna: Create common SMU interfaces for AIE2 and AIE4

Browse source 
AIE2 and AIE4 use similar interfaces to the SMU (System Management
Unit). Move the SMU implementation into aie_smu.c and provide common
interfaces for both platforms.

This allows AIE2 and AIE4 to share the same implementation and reduces
code duplication.
