venus: firmware: Set virtual address rangestracking-qcomlt-fixes-alimon
In order to boot some of the new Venus firmware versions TZ call to set virtual address ranges is needed. Add virtual address ranges for CP and CP_NONPIX in resource structure and use them when loading and booting the firmware on remote processor.
