omap:iommu: early registeration of iommu to handle hwmod dependency.
The DVFS framework for DSP is dependent on hwmod registeration completed for
DSP in iommu driver. This patch moves the iommu initialization to post-core
init to ensure the registeration is completed prior to DVFS stuff.
Without this fix, the following warning was observed during boot-up.
