glamor_largepixmap: Walkaround for large texture's upload.
I met a problem with large texture (larger than 7000x7000)'s uploading on SNB platform. The map_gtt get back a mapped VA without error, but write to that virtual address triggers BUS error. This work around is to avoid that direct uploading. Signed-off-by: Zhigang Gong <zhigang.gong@linux.intel.com>
