ACPI: APD: Add AMD misc clock handler support AMD SoC exposes clock for general purpose use. The clock registration is done in clk-st driver. The MMIO mapping are passed on to the clock driver for accessing the registers. The misc clock handler will create MMIO mappings to access the clock registers and enable the clock driver to expose the clock for use of drivers which will connect to it.
