Since we are quite unlikely to ever face another platform which

uses the i8237 without trying to emulate the PC architecture move
the register definitions for the i8237 chip into the central include
file for the chip, except for the PC98 case which is magic.

Add new isa_dmatc() function which tells us as cheaply as possible
if the terminal count has been reached for a given channel.
