i82378: Remove bogus MMIO coalescing
This MMIO area is an entry gate to legacy PC ISA devices, addressed via
PIO over there. Quite a few of the PIO ports have side effects on access
like starting/stopping timers that must be executed properly ordered
/wrt the CPU. So we have to remove the coalescing mark.
