Jingchang Lu - May 28, 2013, 9:12 a.m.
Add initial support for Freescale Vybrid VF610 SoC.

Signed-off-by: Jingchang Lu <b35083@freescale.com>
---
v4:
  Follow internal suggestions to name the soc name as VF610.
  Use of_clk_init() call initilizing clocks.
v3:
  Split one big arch support patch into small patches.
  Remove unused #include header lines.
  Use common mxc restart function.
