[PATCH 1/4] mach-sunxi: Refactor sunxi SPI-SPL

[Benedikt-Alexander Mokroß]

Hello Jagan,

of course its possible to join them to one file, share the main SPL function and co-exist.
However, SPI-NAND boot isn’t that popular (for good reasons) and only very few sunxi 
SoCs are capable of doing so. Most of the time only one is used and the other
would unnecessary bloat the (very limited) SPL.
Thus I thought it would be much more readable and maintainable if those are 
split in multiple files and distinct functions instead of a lot of #ifdef or similar. 

Anyhow, if the maintainers prefer a single file for any reason, its no big deal to 
reimplement the series and keep everything as one file.

Im going to submit a cover-letter asap.

Best Regards
Benedikt
