[ Upstream commit bec7760a6c5fa59593dac264fa0c628e46815986 ]
The amplifier doesn't loose register state in software shutdown mode, so there is no need to reset the cur_* values.
Without these resets, the amplifier can be turned on after runtime_suspend without waiting for the program and profile to be restored.
