plat-stm32mp1: disable RTCAPB clock when not needed

Disable RTCAPB clock when not used. The clock is currently needed
when enabling or disabling the secondary code since this one reads
secure entry point address from a SoC interface relying on this clock.

Prior this change was RTCAPB clock enabled at boot time and never
disabled. This change disables the clock when secondary core is brought
to life and enables it back before secondary core enters its
power down sequence.
