Prior to this change rx-pad wakeup was done by writing to rx-pad offset value
populated in serial.c idle_init. Now with mux framework support we can use
mux_utilities along with hmwod framework to handle io-pad configuration and
enable rx-pad wake-up mechanism.

This patch (along with a few others) have compile errors when CONFIG_PM
is not set.
