drm/mipi-dbi: Use framebuffer dma-buf helpers

Replace dma_buf_begin_cpu_access() with drm_gem_fb_begin_cpu_access();
same for _end_cpu_access(). Remove some boiler-plate code. No functional
changes.

There's one left-over reference to the imported attachment that we
keep. GEM BOs with imported attachment are considered uncached and
enables special handling within the drm_fb_swab().
