ARM platforms rely on 'ref_clk' of a UFS controller's node in DTS to set up the proper bRefClkFreq for the UFS storage device. The facility is not available on x86. To circumvene that, default the parameter, responsible for carrying the value to the UFS storage device initialization, to the one that Intel's controllers support. This is required to support provisioning of UFS storage devices from userspace, without relying on FW and/or bootloader to make the necessary preparations.
