rS274382: Add workaround for vt efifb's early use of PHYS_TO_DMAP
Summary

In vt_efifb_init the framebuffer's physaddr is passed to PHYS_TO_DMAP before the DMAP is setup. The result is not actually accessed until after the mapping is setup, though. Loosen the assertion in PHYS_TO_DMAP for now, to allow use when dmaplimit == 0.
