[PATCH v6 2/5] scsi: ufs-qcom: name the dev_ref_clk_ctrl registers

[Eric Biggers <ebiggers@kernel.org>]

From: Eric Biggers <ebiggers@google.com>

In preparation for adding another optional register range to the
ufs-qcom driver, name the existing optional register range
"dev_ref_clk_ctrl_mem".  This allows the driver to refer to the optional
register ranges by name rather than index.

No device-tree files actually have to be updated due to this change,
since none of them actually declares these registers.
