Since both the IDE interface and SMC 91C111 Ethernet chip are on-board devices, not SOC devices, move the platform device registration form the common to the board specific code. While at it, remove semicolon (which didn't break compilation only by chance) from the AU1XXX_ATA_DDMA_REQ macro and do some renaming: - change 'au1200_ide0_' variable name prefix to the mere 'ide_'; - change 'smc91x_' variable name prefix to 'smc91c111_' since that's the name of the chip used on the boards; - drop 'AU1XXX_' prefix from the names of macros describing IDE and Ethernet on-board devices; - change 'SMC91111_' to 'SMC91C111_', change 'IRQ' to 'INT' in the names of the macros describing the Ethernet chip for consistency with the IDE macros; - change 'ATA_' to 'IDE_' and 'OFFSET' to 'SHIFT' (since this value is indeed a shift count) in the names of the macros describing the IDE interface.
