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.
