[PATCH] regulator: Kconfig: Fix REGULATOR_QCOM_RPMH dependencies to avoid build error

[John Stultz]

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 REGULATOR_QCOM_RPMH=m which will cause build
failures.

The easy fix here is to remove COMPILE_TEST.

Feedback would be appreciated!
