This patch series adds support for the Realtek System Timer, a 64-bit counter
that serves as a clock event device on Realtek SoCs.

Technical details:
- Implements a 64-bit timer operating at 1MHz fixed frequency.
- Supports oneshot mode and tick broadcast functionality.
- Remains active during CPU power-down states.

Testing:
- Functionality verified for tick broadcast on both RTD1625 and RTD1635 SoCs.
- Confirmed binding documentation passes yamllint, dt_binding_check, and dtbs_check.
- Driver successfully built under COMPILE_TEST.

Patch organization:
Patch 1/2: Device Tree binding documentation
Patch 2/2: Clocksource driver implementation

Best regards,
Hao-Wen Ting
