CMU_APM clock domain provides clocks for APM IP-core (Active Power
Management). According to Exynos850 TRM, CMU_APM generates I3C, Mailbox,
Speedy, Timer, WDT, RTC and PMU clocks for BLK_ALIVE.

This patch adds next clocks:
- bus clocks in CMU_TOP needed for CMU_APM
- all internal CMU_APM clocks
- leaf clocks for I3C, Speedy and RTC IP-cores
- bus clocks for CMU_CMGP and CMU_CHUB

CMU_APM doesn't belong to Power Domains, but platform driver is used for
its registration to keep its bus clock always running. Otherwise rtc-s3c
driver disables that clock and system freezes.

Looks good, could you just resend with the DT binding header changes moved
to the first patch?
