[PATCH RESEND v2 1/2] m68k/atari: add platform device for Falcon IDE port

[Michael Schmitz <schmitzmic@gmail.com>]

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.

  always (suggested by Geert Uytterhoeven <geert@linux-m68k.org>)

Changes from v1

- add error checking for Falcon IDE platform device register
