Arnd Bergmann fcd04aa9b5 interconnect: qcom: fix rpmh link failures
commit 512d4a26abdbd11c6ffa03032740e5ab3c62c55b upstream.

When CONFIG_COMPILE_TEST is set, it is possible to build some
of the interconnect drivers into the kernel while their dependencies
are loadable modules, which is bad:

arm-linux-gnueabi-ld: drivers/interconnect/qcom/bcm-voter.o: in function `qcom_icc_bcm_voter_commit':
(.text+0x1f8): undefined reference to `rpmh_invalidate'
arm-linux-gnueabi-ld: (.text+0x20c): undefined reference to `rpmh_write_batch'
arm-linux-gnueabi-ld: (.text+0x2b0): undefined reference to `rpmh_write_batch'
arm-linux-gnueabi-ld: (.text+0x2e8): undefined reference to `rpmh_write_batch'
arm-linux-gnueabi-ld: drivers/interconnect/qcom/icc-rpmh.o: in function `qcom_icc_bcm_init':
(.text+0x2ac): undefined reference to `cmd_db_read_addr'
arm-linux-gnueabi-ld: (.text+0x2c8): undefined reference to `cmd_db_read_aux_data'

The exact dependencies are a bit complicated, so split them out into a
hidden Kconfig symbol that all drivers can in turn depend on to get it
right.
