According to DRA7x TRM section 4.3.5 Realtime Counter (Master Counter),
the realtime counter sits in the Wakeup Always-On Power domain.
Furthermore, the counter will automatically switch the 32K clock source
when MPU goes into standby and automatically switch back to SYS_CLK or
ABE_LP when MPU goes out of standby.
