[PATCH v2 0/2] Do not gate ge0/1 and runit clocks on Kirkwood

kernel 3.8-rc5 will hang on kirkwood DT if the Ethernet driver is built
as a module or when no driver claiming the runit clock is built in. 
(Usually, at least the serial driver is built in, but it won't request
the clock if "clock-frequency" is given in DT.) In the past, we fixed
this by keeping the clocks ticking.

These two patches re-enable the ethernet fix for DT and declare the
"runit" clock as not to gated even if unused.



- Do not turn on ge[01] clocks unconditionally. Instead, fix the
  previous way we handled this on kirkwood.

  ARM: kirkwood: Ensure that kirkwood_ge0[01]_init() finds its clock
