Hao-Wen Ting d1780dce95 clocksource/drivers: Add Realtek system timer driver 
Add a system timer driver for Realtek SoCs.

This driver registers the 1 MHz global hardware counter on Realtek
platforms as a clock event device. Since this hardware counter starts
counting automatically after SoC power-on, no clock initialization is
required. Because the counter does not stop or get affected by CPU power
down, and it supports oneshot mode, it is typically used as a tick
broadcast timer.
