Unify the flow in pwr_reg_rdwr() with intel_scu_ipc_dev_command_with_size().
While read buffer is not currently being used by the callers of
pwr_reg_rdwr(), this might change in the future. For the existing code
it's a harmless change because the read data for the write operation
is simply discarded.
