[PATCH -next] regulator: qcom-rpmh: fix build after QCOM_COMMAND_DB is tristate

From: Randy Dunlap
Date: Fri Dec 25 2020 - 13:54:00 EST


Restrict REGULATOR_QCOM_RPMH to QCOM_COMMAND_DB it the latter is enabled.

Fixes this build error:
microblaze-linux-ld: drivers/regulator/qcom-rpmh-regulator.o: in function `rpmh_regulator_probe':
(.text+0x354): undefined reference to `cmd_db_read_addr'

Fixes: 778279f4f5e4 ("soc: qcom: cmd-db: allow loading as a module")
