drm/buddy: Move internal helpers to buddy.c
Move gpu_buddy_block_state(), gpu_buddy_block_is_allocated(),
and gpu_buddy_block_is_split() from gpu_buddy.h to gpu_buddy.c
as static functions since they have no external callers.
Remove gpu_get_buddy() as it was an unused exported wrapper
around the internal __get_buddy().
No functional changes.
v2:
- Rebased after DRM buddy allocator moved to drivers/gpu/
- Keep gpu_buddy_block_is_free() in header since it's now
used by drm_buddy.c
- Updated commit message
