[ 01/95] ARM: OMAP: make iommu subsys_initcall to fix builtin omap3isp

[Greg KH]

3.2-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Ohad Ben-Cohen <ohad@xxxxxxxxxx>

commit 435792d93410f008120c4dbab148019a3cc31dbc upstream.

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.
