regulator: qcom-smd: make smd_vreg_rpm static

Since smd_vreg_rpm is used only in
drivers/regulator/qcom_smd-regulator.c, make it static and fix the
following sparse warning:

drivers/regulator/qcom_smd-regulator.c:14:21: sparse: warning:
symbol 'smd_vreg_rpm' was not declared. Should it be static?

No functional changes intended.
