[PATCH v3 1/4] ARM: mach-moxart: add MOXA ART SoC files

[jonas.jensen@gmail.com (Jonas Jensen)]

Add MOXA ART SoC support.

The MOXA ART SoC is based on a Faraday FA526 ARMv4 32-bit 192 MHz CPU
with MMU and 16KB/8KB D/I-cache (UC-7112-LX).

Notes:
    Applies to next-20130703
    
    Changes since v2:
    
    1. add CLKSRC_MMIO and GENERIC_CLOCKEVENTS to ARCH_MOXART
    2. call of_clk_init(NULL) from .init_time hook
