ARM: SAMSUNG: Add platform support code for OneNAND controller

This patch adds setup code for Samsung OneNAND controller driver. The
driver needs to be aware on which SoC it is running, so the actual
device id is being changed in cpu init code. S3C64xx SoCs have 2 OneNAND
controllers while S5PC100 and S5PC110 has only one.
