The "-ffixed-r15" option doesn't work well for gcc4. Since we
don't use gp for small data with option "-G0", we can use gp
as global data pointer. This allows compiler to use r15. It
is necessary for gcc4 to work properly.

This patch adds driver for a trivial gpio core, which is described
in http://nioswiki.com/GPIO. It is used for gpio led and nand flash
interface in u-boot.
When CONFIG_SYS_GPIO_BASE is not defined, board may provide
its own driver.

This helps to clean up the include/ directory so that it only contains
non-architecture-specific headers and also matches Linux's directory
layout which many U-Boot developers are already familiar with.
