media: venus: firmware: Set virtual address ranges

Browse Source 
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.
