powerpc/ide: remove mpc8xx-ide driver 

This driver was only used by arch/ppc code and is obsolete
now with the move to common arch/powerpc code.

[bart: port it over IDE tree, remove leftover 'choice' from Kconfig]

---help---
Select how the IDE devices are connected to the MPC8xx system:
8xx_PCCARD uses the 8xx internal PCMCIA interface in combination
with a PC Card (e.g. ARGOSY portable Hard Disk Adapter),
ATA PC Card HDDs or ATA PC Flash Cards (example: TQM8xxL
systems)
8xx_DIRECT is used for directly connected IDE devices using the 8xx
internal PCMCIA interface (example: IVMS8 systems)
EXT_DIRECT is used for IDE devices directly connected to the 8xx
bus using some glue logic, but _not_ the 8xx internal
PCMCIA interface (example: IDIF860 systems)
