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This driver was only used by arch/ppc code and is obsolete now with the move to common arch/powerpc code.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] Signed-off-by: Arnd Bergmann <arnd@arndb.de> Acked-by: Kumar Gala <galak@kernel.crashing.org> Cc: Paul Mackerras <paulus@samba.org> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
