accel/ivpu: Use dma_resv_lock() instead of a custom mutex
This fixes a potential race conditions in:
- ivpu_bo_unbind_locked() where we modified the shmem->sgt without
holding the dma_resv_lock().
- ivpu_bo_print_info() where we read the shmem->pages without
holding the dma_resv_lock().
Using dma_resv_lock() also protects against future syncronisation
issues that may arise when accessing drm_gem_shmem_object or
drm_gem_object members.
