[PATCH 06/10] ARM: mx28: update clocks for dual fec support

[Shawn Guo]

* Change fec clock registration to use con_id only for looking up,
  so that dual fec driver can find the same clock for both fec0
  and fec1.

* Explicitly call clk_enable for some clocks that have been on to
  reflect the clock status and get usecount updated. Otherwise,
  clocks could be turned off by pair call of clk_enable/clk_disable
  in drivers, because of the incorrect initial usecount.
