Gwan-gyeong Mun d028a7690d drm/i915/dmabuf: Fix prime_mmap to work when using LMEM
The current implementation of i915 prime mmap only works when initializing
drm_i915_gem_object with shmem_region.
When using LMEM, drm_i915_gem_object is initialized with ttm_system_region.
In order to make prime mmap work even this case, when using LMEM
(when using ttm in i915), dma_buf_ops.mmap callback function calls
drm_gem_prime_mmap(). drm_gem_prime_mmap() of drm core calls internally
i915_gem_mmap() so that prime mmap can perform normally.
The fake offset is processed inside drm_gem_prime_mmap().

Testcase: igt/prime_mmap
