f8b6e9145c CPLD: Pull up HOST_SYNC signal, which is usually floating.
HOST_SYNC is only connected to connector P28, and is therefore not driven (left to float) unless connected to some synchronization signal. Pull it up to keep it steady.

In doing so, I had to switch all unused pins to pull-up, and all input-only and tri-state pins to float. All input/tri-state pins except for HOST_SYNC are tied to the microcontroller and can be pulled up there.
