soc/soc/intel: Add UFS device with ref-clk-freq property

UFS storage devices require the bRefClkFreq attribute to be set to
operate correctly in high speed mode. The correct value is determined by
what the SoC / board supports. For the ADL UFS controller, it is
19.2 MHz.

a) Introduce a new ACPI property "ref-clk-freq".
b) Add support to configure this property using an SoC Kconfig.

BUG=b:238262674
TEST=Build,boot Nirwen and dump SSDT entries and check that the kernel
correctly parses ref-clk-freq as 19.2 MHz.
