Autoloading of Falcon IDE driver modules requires converting
these drivers to platform drivers.

Add platform device for Falcon IDE interface in Atari platform
setup code in preparation for this.

Changes from RFC

- fix region size (spotted by Szymon Bieganski <S.Bieganski@chello.nl>)
- define IDE interface address in atari/config.c, create platform device
  always (suggested by Geert Uytterhoeven <geert@linux-m68k.org>)

Changes from v1

- add error checking for Falcon IDE platform device register
