Merge branch 'prima2/soc' into next/soc

From Barry Song <Barry.Song@csr.com>:

SiRFatlas6 is much similar with SiRFprimaII with some changes about:
1. deleted l2 cache, sdmmc4, multimedia and so on
2. changed pinmux layout and clock layout
3. DMA access limitation disappears, that makes us not need DMA_ZONE
   on atlas6

* prima2/soc:
  ARM/dts: prima2: add .dtsi for atlas6 and .dts for atla6-evb board
  arm: prima2: add new SiRFatlas6 machine in common board
