ADL finds multiple logical gpus, this commit avoids multiple
unneeded initializations of AmdGpu class. The main control is moved to
AmdGpuGroup and the ADL_* calls are updated to ADL2_*, using the
context. Adapters using PMlog should be initialized only if sensors are
detected, adapters that pmlog is not enabled or doesn't work, should
fallback previous logic.
