From: Eric Biggers <ebiggers@xxxxxxxxxx>
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.
