ARM: sunxi: Basic Allwinner A10/A13 (sun4i/sun5i) support

This adds support for the Allwinner A10/A13 SoC's. Additionally
board support for the dev-boards sun4i/sun5i is added.

NOTES (remove in final version before submission):
Additionally, I did put some comments for further cleanup into the
code. Search for "test-only" to find those.

And should Tom's email address be changed? He is not working for Allwinner
any more. Correct?

ARM sunxi: Basic GPIO driver

GPIO driver for Allwinner sun4i/sun5i family of SoCs

GPIO Pins are named by their symbolic pin names P<g><#>
such as PH19 or H19.

Note: This do not perform any validation if the pin is in use
for some other I/O function. Use with care.
tools: mksunixboot adding a Allwinner boot header

This tool adds a boot header to the supplied file, for booting
code directly from the SoC embedded boot rom. Needed for making
the SPL loader bootable.
