[PATCH V3 08/10] ARM: sirf: add atlas7 machine support

[Barry Song]

From: Zhiwu Song <Zhiwu.Song at csr.com>

atlas7 is next-gen auto soc from CSR.
It could bring to customers most integrated SoC solution:
- World leading Bluetooth 4.0 and GNSS baseband
- Audio processing, analog CODEC and ADC by DSP
- Analog video input
- SDR accelerators
- CAN bus support by Cortex-M3
