SoC platform changes. Main theme this merge window:
- The Netx platform (Netx 100/500) platform is removed by Linus Walleij--
the SoC doesn't have active maintainers with hardware, and in
discussions with the vendor the agreement was that it's OK to remove.
- Russell King has a series of patches that cleans up and refactors
SA1101 and RiscPC support.
