Add Amiga Gayle PATA controller driver. It enables libata support
for the on-board IDE interfaces on some Amiga models (A600, A1200,
A4000 and A4000T) and also for IDE interfaces on the Zorro expansion
bus (M-Tech E-Matrix 530 expansion card).
Thanks to John Paul Adrian Glaubitz and Michael Schmitz for help
with testing the driver.
