scsi: ufs-qcom: change device reference clock control
As of HW major version 2, bit 'UFS_DEV_REF_CLK_EN' which is used to
gate/ungate the ref_clk to external UFS device, was moved into the
UFS register space to UFS_CFG1 register. This change adds support
to appropriately control the device reference clock and it also
adds the missing documentation for the device reference clock control
register address space.
