[PATCH] drm/i915/gvt: add cmd_access flag for 2 MMIO to avoid log flood

[Pei Zhang]

If guest is accessing an un-expected mmio through cmd, gvt will print an
error log. In some special case, the guest cmd access of such mmio is
very huge which cause the error log flood. Add F_CMD_ACCESS flag to 2 new
found mmio to avoid log flood.
