A built-in regulator driver cannot link against a modular cmd_db driver:
qcom-rpmh-regulator.c:(.text+0x174): undefined reference to `cmd_db_read_addr'
There is already a dependency for RPMh, so add another one of this
type for cmd_db.
Fixes: 34c5aa2666db ("regulator: Kconfig: Fix REGULATOR_QCOM_RPMH dependencies to avoid build error")
Fixes: 46fc033eba42 ("regulator: add QCOM RPMh regulator driver")

Add NXP PF8100/PF8121A/PF8200 regulator driver. PF8100/PF8121A/PF8200 is PMIC designed for highperformance consumer applications. It features seven high efficiency buck, four linear and one vsnvs regulators. Tested in Engicam i.Core MX8M Mini SOM platform boards.

The kernel test robot reported the following build error: All errors (new ones prefixed by >>): xtensa-linux-ld: drivers/regulator/qcom-rpmh-regulator.o: in function `rpmh_regulator_vrm_get_voltage_sel': qcom-rpmh-regulator.c:(.text+0x270): undefined reference to `rpmh_write' xtensa-linux-ld: drivers/regulator/qcom-rpmh-regulator.o: in function `rpmh_regulator_send_request': qcom-rpmh-regulator.c:(.text+0x2f2): undefined reference to `rpmh_write' xtensa-linux-ld: drivers/regulator/qcom-rpmh-regulator.o: in function `rpmh_regulator_vrm_get_voltage_sel': >> qcom-rpmh-regulator.c:(.text+0x274): undefined reference to `rpmh_write_async' xtensa-linux-ld: drivers/regulator/qcom-rpmh-regulator.o: in function `rpmh_regulator_send_request': qcom-rpmh-regulator.c:(.text+0x2fc): undefined reference to `rpmh_write_async' Which is due to REGULATOR_QCOM_RPMH depending on QCOM_RPMH || COMPILE_TEST. The problem is that QOM_RPMH can now be a module, which in that case requires REGULATOR_QCOM_RPMH=m to build. However, if COMPILE_TEST is enabled, REGULATOR_QCOM_RPMH can be set to =y while QCOM_RPMH=m which will cause build failures. The fix here is to add (QCOM_RPMH=n && COMPILE_TEST) to the dependency. Feedback would be appreciated!
