video: camera: Fix rtcpu build for Linux v5.14

Browse Source 
The RTCPU driver fails to build with Linux v5.14 as an out-of-tree
module because the return type of the bus_type remove callback is int
and not void. Make the necessary changes to allow the RTCPU driver to
build for Linux v5.14+ kernels.
