IDE subsystem has been deprecated since 2009 and the majority
(if not all) of Linux distributions have switched to use
libata for ATA support exclusively.  However there are still
some users (mostly old or/and embedded non-x86 systems) that
have not converted from using IDE subsystem to libata PATA
drivers.  This doesn't seem to be good thing in the long-term
for Linux as while there is less and less PATA systems left
in use:

* testing efforts are divided between two subsystems

* having duplicate drivers for same hardware confuses users

This patch converts amigaone_defconfig to use libata PATA
drivers.

Build tested only.
If you have affected hardware please test.  Thank you.

Thanks for cleaning up the defconfig file!

libata drivers work fine on the amigaone platform (tested on all three
first-gen AmigaOne machines). BTW: could it be that CONFIG_ATA_SFF=y
and CONFIG_ATA_BMDMA=y are missing in the patch?

br,

Thank you for testing!

When it comes to CONFIG_ATA_SFF and CONFIG_ATA_BMDMA there is no need
to explicitly enable them because once CONFIG_ATA is enabled they both
are also enabled by default (they both have 'default y' in Kconfig).

[ defconfig changes in the patch were obtained by:
  - doing 'make amigaone_defconfig'
  - changing IDE options to libata ones using 'make menuconfig'
  - doing 'make savedefconfig'
  - doing 'diff -u arch/powerpc/configs/amigaone_defconfig defconfig'
  so there should be no missing options etc. ]

Applied to powerpc next, thanks.
