Subject: [PATCH v2 3/4] drm: init TTM dev_mapping in ttm_bo_device_init()
With dev->anon_inode we have a global address_space ready for operation
right from the beginning. Therefore, there is no need to do a delayed
setup with TTM. Instead, set dev_mapping during initialization in
ttm_bo_device_init() and remove any if (dev_mapping) conditions.
