staging: vc04_services: Replace vchiq_status return type to int
Modify the functions' signature using enum vchiq_status to return int.
Currently, this patch only touches the function signatures and
in subsequent patches each vchiq_status enumerated value will be
replaced by a integer value.
This patch acts as an initial point to address the TODO item:
* Get rid of custom function return values
for vc04_services/interface.
