Tyan S8226: Fix incompatible pointer warning
Fix warning: mptable.c:52, GNU Compiler 4 (gcc), Priority: Normal passing argument 3 of 'mptable_write_buses' from incompatible pointer type [enabled by default] mptable_write_buses is expecting a pointer to an int, so I changed the U8 isa_bus to an int to match. A U8 doesn't make sense if the value could be greater than 255 - certainly unlikely, but possible since the value of isa_bus gets set to the maximum PCI bus number + 1.
