libata/drivers: Add driver for Apple "MacIO" IDE controller
This is a libata driver for the "macio" IDE controller used on most Apple
PowerMac and PowerBooks. It's a libata equivalent of drivers/ide/ppc/pmac.c
It supports all the features of its predecessor, including mediabay hotplug
and suspend/resume. It should also support module load/unload.
The timing calculations have been simplified to use pre-calculated tables
compared to drivers/ide/pmac.c and it uses the new mediabay interface
provided by a previous patch.

+ Most IDE capable PowerMacs have IDE busses driven by a variant
+ of this controller which is part of the Apple chipset used on
+ most PowerMac models. Some models have multiple busses using
+ different chipsets, though generally, MacIO is one of them.
