staging: vc04_services: Drop vchiq_connected.[ch] files

The vchiq_connected.[ch] just implements two function:

- vchiq_add_connected_callback()
- vchiq_call_connected_callbacks()

for the deferred vchiq callbacks. Those can easily live in
vchiq_arm.[ch], hence move them. This allows making the
vchiq_call_connected_callbacks() function static.

The move doesn't copy over MAX_CALLBACKS because it is the same as
VCHIQ_DRV_MAX_CALLBACKS. Hence, it now being used in
vchiq_add_connected_callback().

No functional changes intended in this patch.
