media: venus: assign unique bus_info strings for encoder and decoder
The Venus encoder and decoder video devices currently report the same
bus_info string ("platform:qcom-venus").
Assign unique bus_info identifiers by appending ":dec" and ":enc" to the
parent device name. With this change v4l2-ctl will display two separate
logical devices
