qcacld-3.0: Fix agc registers dump logic to avoid fw assert

Propagation from qcacld-2.0 to qcacld-3.0

- Current AGC registers dump logic is not correct and its not
  reading correct target registers
- Add correct AGC register read recipe to read correct AGC data
- Wake up SoC before reading any target register
