On Sparc and PowerMac, the bit 0 of the address selects the register type (control or data) and bit 1 selects the channel (B or A). On m68k Macintosh and NeXTcube, the bit 0 selects the channel and bit 1 the register type. This patch introduces a new parameter (bit_swap) to the device interface to indicate bits usage must be swapped between registers and channels. For the moment all the machines use the bit 0, but this change will be needed to emulate the Quadra 800 or NeXTcube machine.
