vgahw: Don't default to standard (port space) access routines

In fact, don't default to anything; drivers must explicitly say which
kind they want, and they are strongly encouraged to do MMIO if possible.
This is an ABI change in that drivers that don't will crash, but drivers
that are explicit will work with both old and new servers.
