Subject: [PATCH 4/6] ARM: OMAP: add SoSSI clock (remove manual checking of SoSSI state from idle)

From: Imre Deak <imre.deak@...idboot.com>

The SoSSI driver should already take care of this by enabling / disabling
its clock when necessary, so this legacy callout from the PM idle code
is not needed any more.
