hw/vesa: Switch trap handling to use MMIO handler

To be able to use the VESA device with the new generic I/O trap handler,
we need to use the different MMIO handler callback routine.

Replace the existing dummy in and out handlers with a joint dummy
MMIO handler, and register this using the new registration function.
