Subject: [PATCH] remoteproc: qcom: fix RPMSG_QCOM_GLINK_SMEM dependencies

When RPMSG_QCOM_GLINK_SMEM=m and one driver causes the qcom_common.c file
to be compiled as built-in, we get a link error:

drivers/remoteproc/qcom_common.o: In function `glink_subdev_remove':
qcom_common.c:(.text+0x130): undefined reference to `qcom_glink_smem_unregister'
qcom_common.c:(.text+0x130): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `qcom_glink_smem_unregister'
drivers/remoteproc/qcom_common.o: In function `glink_subdev_probe':
qcom_common.c:(.text+0x160): undefined reference to `qcom_glink_smem_register'
qcom_common.c:(.text+0x160): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `qcom_glink_smem_register'

Out of the three PIL driver instances, QCOM_ADSP_PIL already has a
Kconfig dependency to prevent this from happening, but the other two
do not. This adds the same dependency there.
