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

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'
