remoteproc: qcom: q6v5: fix service routines build errors

When CONFIG_QCOM_AOSS_QMP=m and CONFIG_QCOM_Q6V5_MSS=y, the builtin
driver cannot call into the loadable module's low-level service
functions. Trying to build with that config combo causes linker errors.

There are two problems here. First, drivers/remoteproc/qcom_q6v5.c
should #include <linux/soc/qcom/qcom_aoss.h> for the definitions of
the service functions, depending on whether CONFIG_QCOM_AOSS_QMP is
set/enabled or not. Second, the qcom remoteproc drivers should depend
on QCOM_AOSS_QMP iff it is enabled (=y or =m) so that the qcom
remoteproc drivers can be built properly.

This prevents these build errors:

aarch64-linux-ld: drivers/remoteproc/qcom_q6v5.o: in function `q6v5_load_state_toggle':
qcom_q6v5.c:(.text+0xc4): undefined reference to `qmp_send'
aarch64-linux-ld: drivers/remoteproc/qcom_q6v5.o: in function `qcom_q6v5_deinit':
(.text+0x2e4): undefined reference to `qmp_put'
aarch64-linux-ld: drivers/remoteproc/qcom_q6v5.o: in function `qcom_q6v5_init':
(.text+0x778): undefined reference to `qmp_get'
aarch64-linux-ld: (.text+0x7d8): undefined reference to `qmp_put'
