SAUCE remove unnecessary suspend/resume functions

BugLink: http://bugs.launchpad.net/bugs/882723
Disabling/re-enabling clocks is not necessary as it's done in *_startup()
and *_shutdown() functions, and shall be performed during suspend/resume.

This is causing warnings of un-matched clk_enable()/clk_disable()

Rework patch for imx_3.0.15 code base
