Michael Schmitz 5ed0794cde m68k/atari: Convert Falcon IDE drivers to platform drivers 
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. Use this in the pata_falcon driver in place of the simple
platform device set up on the fly.

Convert falconide driver to use the same platform device that is used
by pata_falcon also. (With the introduction of a platform device for
the Atari Falcon IDE interface, the old Falcon IDE driver no longer
loads (resource already claimed by the platform device)).

Tested (as built-in driver) on my Atari Falcon.

* This function does a reset on machines that lack the ability to

*
* To get the values at addresses 0 and 4, the MMU better is turned
* off first. After that, we have to jump into physical address space
* (the PC before the pmove statement points to the virtual address of
* the code). Getting that physical address is not hard, but the code
* becomes a bit complex since I've tried to ensure that the jump
* statement after the pmove is in the cache already (otherwise the
* processor can't fetch it!). For that, the code first jumps to the
* jump statement with the (virtual) address of the pmove section in
* an address register . The jump statement is surely in the cache
* now. After that, that physical address of the reset code is loaded
* into the same address register, pmove is done and the same jump
* statements goes to the reset code. Since there are not many
* statements between the two jumps, I hope it stays in the cache.
*
* The C code makes heavy use of the GCC features that you can get the
