ARM: OMAP: make iommu subsys_initcall to fix builtin omap3isp

Browse Source 
omap3isp depends on omap's iommu and will fail to probe if
initialized before it (which always happen if they are builtin).

Make omap's iommu subsys_initcall as an interim solution until
the probe deferral mechanism is merged.
