Embedding struct ata_ioports into struct ide_port saves us an allocation.
Making it available to client drivers is necessary to give them access
to struct ata_port which is needed in the next patch.

To get persistent devicenames under /dev/ allow to set the
devicename from the driver instead of using "ata" unconditionally.

Currently we only support oldschool IDE SFF devices. This is done
by registering a register layout struct and everything else is done
by the generic IDE SFF driver. Since modern ATA devices still use
ATA, but not the SFF interface anymore, split out the IDE SFF support
to a separate file to allow for other types of ata interfaces.

This simple driver enables a generic driver for ATA type of devices to get
access to the so called 'register file' of an ATA drive.
