Summary

Implement driver for the RTC embedded in the RK805/RK808 power management system.

This is a replacement for D22692, taking into account comments on than revision. Based on experiments on my RK808, setting the time doesn't alter the internal/inaccessible sub-second counter, therefore there's no point in calling clock_schedule().

Test Plan

Tested using the RK808-D on my RockPro64 (RK3399)
