staging: vchiq_arm: fix enum vchiq_status return types

commit 7d83299351fe7c812c529f5e39fe63b5312e4233 upstream.

gcc-13 notices a type mismatch between function declaration
and definition for a few functions that have been converted
from returning vchiq specific status values to regular error
codes:

drivers/staging/vc04_services/interface/vchiq_arm/vchiq_arm.c:662:5: error: conflicting types for 'vchiq_initialise' due to enum/integer mismatch; have 'int(struct vchiq_instance **)' [-Werror=enum-int-mismatch]
drivers/staging/vc04_services/interface/vchiq_arm/vchiq_arm.c:1411:1: error: conflicting types for 'vchiq_use_internal' due to enum/integer mismatch; have 'int(struct vchiq_state *, struct vchiq_service *, enum USE_TYPE_E)' [-Werror=enum-int-mismatch]
drivers/staging/vc04_services/interface/vchiq_arm/vchiq_arm.c:1468:1: error: conflicting types for 'vchiq_release_internal' due to enum/integer mismatch; have 'int(struct vchiq_state *, struct vchiq_service *)' [-Werror=enum-int-mismatch]

Change the declarations to match the actual function definition.
