Subject: [PATCH] drm/legacy: Fix type for drm_local_map.offset

drm_local_map.offset is not only used for resource_size_t but also
dma_addr_t which may be of different sizes.

Reported-by: Nathan Chancellor <natechancellor@...il.com>
Fixes: 8e4ff9b56957 ("drm: Remove the dma_alloc_coherent wrapper for internal usage")
