soc: qcom: hab: add some more physical channels 



These new physical channels are supposed to support the
cross-VM communication in the multiple-GVM set up.
To actually enable such support, some additional changes
(e.g, add some new vdev-shmem items in the relevant
linux-*.config files, and some changes in the relevant GVMs'
.dtb files) will be needed.
