ARM: OMAP2+: Remove legacy smsc911x and smc91x GPMC support
When connecting an ethernet chip to the GPMC, such as smc91x or smsc911x, a GPIO has to be requested to be used as an IRQ and also the IO memory for a GPMC chip-select. When booting with DT the chip-select allocation is handled in a generic manner in the GPMC driver and the GPIO to IRQ mapping is made by the DT core so this code is not needed anymore now that mach-omap2 related boards are DT-only.
