[COMMON] iommu/exynos: support secure sysmmu interrupt

Abnormal situation like page fault can be happened when sysmmu is
operating in secure context. To ease debugging with maintaining secure
state, secure interrupt handler is added. In this handler, useful
information of sysmmu status can be obtained through exynos_smc().
