devmem, x86: PAT Change /dev/mem mmap with O_SYNC to use UC_MINUS
All kernel mappings like ioremap(), etc uses UC_MINUS as the type. /dev/mem mappings with /dev/mem being opened with O_SYNC however was using UC, resulting in a conflict with /dev/mem mmap failing. This seems to be affecting some apps (one being flashrom) which are using O_SYNC and which were working before. Switch /dev/mem with O_SYNC also to UC_MINUS.
