wifi: ath10k: fix QCOM_RPROC_COMMON dependency

[ Upstream commit 21ae74e1 ]

If ath10k_snoc is built-in, while Qualcomm remoteprocs are built as
modules, compilation fails with:

/usr/bin/aarch64-linux-gnu-ld: drivers/net/wireless/ath/ath10k/snoc.o: in function `ath10k_modem_init':
drivers/net/wireless/ath/ath10k/snoc.c:1534: undefined reference to `qcom_register_ssr_notifier'
/usr/bin/aarch64-linux-gnu-ld: drivers/net/wireless/ath/ath10k/snoc.o: in function `ath10k_modem_deinit':
drivers/net/wireless/ath/ath10k/snoc.c:1551: undefined reference to `qcom_unregister_ssr_notifier'

Add corresponding dependency to ATH10K_SNOC Kconfig entry so that it's
built as module if QCOM_RPROC_COMMON is built as module too.
