Log:
wcte12xp, wctdm24xxp: Add call to 'pci_set_mwi' on initialization.

I have yet to personally come across a system where this actually
changes the observable behavior, but it certainly seems like the sane
thing to do and I would rather not let this float around as a patch when
I can just merge it in.
