Log Message:
Pull up revision 1.225 (requested by bouyer in ticket #653):
Add an optionnal controller callback for channel reset. If the callback
is set to NULL, use the generic reset code.
Use this to work around a bug in some Acer IDE controllers (like the
one found in some sparc systems) where a controller disable/enable
is required after a reset to avoid data corruption when Ultra-DMA is
used. Workaround from opensolaris, thanks to Hiroki Sato for testing.
