Since both the IDE interface and SMC 91C111 Ethernet chip are on-board devices,
move the platform device registration form the common to board specific code.
While at it, do some renaming:
- change 'au1200_ide0_' variable name prefix to the mere 'ide_';
- change 'smc91x_' variable name prefix to 'smc91c111_';
- drop 'AU1XXX_' prefix from the macro names;
- change 'SMC91C111_' to 'SMC91C111_', change 'IRQ' to 'INT' for consistency
in the Ethernet chip macro names;
- change 'ATA_' to 'IDE_' and 'OFFSET' to 'SHIFT' (since this value is indeed
a shift count) in the IDE interface macro names.

Oops, needed one more rename. :-)
This patch is atop of my two recent SMC 91C1111 platform device fixes.
It has only been compile tested...
