LFU-373 imx8ulp: upower: Do not send AFFB enable message for A1
On A1 part, upower ROM will default enable AFFB for APD/AVD/RTD before
power on domains. We don't need to send the AFFB enable message
any more. Actually enabling the AFFB of APD should happen during power
mode switch which needs put APD to hold mode. It is hard to implement
for boot, so upower ROM's implementation is necessary and simple.
