Because it computes the memory region on the fly for every update (with memory_region_find), it cannot enable/disable logging by itself. We could always treat updates as invalidations if dirty logging is not enabled, assuming that the board will enable logging on the RAM region that includes the framebuffer. However, the function is unused, so just drop it.
