[U-Boot] V4 S3C64XX: Switch all I/O to use readl/writel functio and Clear SMDK64XX

[Zhong Hongbo]

V4:
1. Adjust SPL patch order
2. seperate the patch of "arm1176: Fixed No relocation.", It is a common issue for arm
platform. I sent it for other thread. 

V3:
1. Replace ELFIN with S3C64XX for all the variable of cpu.h.
2. Change __S3C6400_H__ into __CPU__H__.
3. Use C language to implement memory initialization.
4. Use C language to re-write reset function.
5. Delete u-boot-nand.lds.

V2:
1. Modify the type of return for s3c64xx_get_base_nand
2. Add patch 0014 to support s3c6410 board
3. Adjust patch for mix content.

V1:
This serial patch intent to:
1. Switch all I/O to use readl/writel function
2. Change nand_spl to use SPL framework
3. S3C64XX serial includes s3c6400 and s3c6410,
Here seprate cpu and board file to support to board's of s3c6410.


I test this patch on my s3c6410 development board. the log as following:
