This is non-functional change to prepare the device cgroup code
for adding eBPF-based controller for cgroups v2.
The patch performs the following changes:
1) __devcgroup_inode_permission() and devcgroup_inode_mknod()
are moving to the device-cgroup.h and converting into static inline.
2) __devcgroup_check_permission() is exported.
3) devcgroup_check_permission() wrapper is introduced to be used
by both existing and new bpf-based implementations.
