From: Arnd Bergmann <arnd@arndb.de>

The AHB driver depends on the remoteproc interface, which could
be in a loadable module when ath12k itself is built-in:

arm-linux-gnueabi-ld: drivers/net/wireless/ath/ath12k/ahb.o: in function `ath12k_ahb_probe':
ahb.c:(.text+0xb2c): undefined reference to `qcom_register_ssr_notifier'
arm-linux-gnueabi-ld: ahb.c:(.text+0x1000): undefined reference to `qcom_unregister_ssr_notifier'
arm-linux-gnueabi-ld: drivers/net/wireless/ath/ath12k/ahb.o: in function `ath12k_ahb_remove':
ahb.c:(.text+0x1146): undefined reference to `qcom_unregister_ssr_notifier'

Add a dependency to only allow the AHB portion to be enabled if either
remoteproc support is built-in or ath12k is itself a loadable module.

A better way to fix this would be to make the driver more modular and
ensure the AHB and PCI components are built into separate loadable modules
like it is done for the ATH10K driver, but that is a much larger rework
that someone else can do in the future.
