powerpc/rcpm: add sleep support for T4/B4 chips
RCPM unit controls the power managment of T4/B4 chips. Software can
access RCPM registers to put specific thread/core in PH10/PH15/PH20/PH30
state or put the device in LPM10/LPM20/LPM40 mode.
The RCPM unit supports several wake up sources through internal timers
and internal and external interrupts.
When the device enter sleep state, it will be put in LPM20 mode.
The command is "echo standby > /sys/power/state".
