  firmware: exynos-acpm: add empty method to allow compile test (2025-10-22 07:49:38 +0200)

----------------------------------------------------------------
Samsung SoC firmware/clock drivers for v6.19

Extend Samsung ACPM (Alive Clock and Power Manager) firmware drivers:
1. Add support for passing DVFS (Dynamic Voltage and Frequency) messages
   to configure the clocks in ACPM device.

2. Add Exynos ACPM clock driver, which exposes to Linux several clocks
   handled by the ACPM (firmware).
