modem/msm-modem: rename msm-modem-mainline to msm-modem-rpmsg

Newer Qualcomm SoCs (e.g. SDM845. MSM8953) seem to use a different method to talk to the modem. There are no longer separate rpmsg/SMD channels for QMI messags, instead the modem is also available through QRTR.

On these newer SoCs, installing msm-modem-mainline is pointless, because the created /dev/modem device will not actually allow communicating with the modem. However, you still need the part from the base package (msm-modem), which installs+enables rmtfs.

To avoid confusion, rename the msm-modem-mainline subpackage to msm-modem-rpmsg. Install only "msm-modem" on SDM845 because that likely does not allow communication with the modem through RPMSG anyway.

This sounds like a good way forward. Out of interest could you point me to some docs on getting qmicli or ofonoctl going through qrtr? There doesn't seem to be much on it and I'd like to see if I can talk to the modem and update the sdm845 wiki page accordingly.

This needs proper documenting and more important, testing from sdm845 owners
