OMAP: hwmod: Fix wrong pointer iteration in oh->slaves
The iteration is currently done on the omap_hwmod_ocp_if pointer and not on the table pointer that reference them. It worked most of the time because the structure are contiguous in memory. Signed-off-by: Benoit Cousson <b-cousson@ti.com> Signed-off-by: Paul Walmsley <paul@pwsan.com>
