[PATCHV2 REPOST 6/7] ARM: OMAP3 PM: Remove IO Daisychain control from cpuidle

Vishwanath BS [off-list ref] writes:

As IO Daisy chain sequence is triggered via hwmod mux, there is no need to
control it from cpuidle path for OMAP3.

Also as omap3_disable_io_chain is no longer being used, just remove the function.

In the TRM (4460 public TRM vM) it says:

  "The software must enable the I/O wakeup prior entering a low-power
   mode and disable it following a wake-up event."

but after this series, once it's enabled, it is never disabled.   What
am I missing?
