Move irq_domain_add_legacy call from imx5*-dt.c into tzic init function and have the tzic driver adopt irqdomain support for both DT and non-DT boot. Now tzic init function calls irq_alloc_descs to get irq_base and adds a lenacy irqdomain with the irq_base, so that the mapping between tzic irq and Linux irq number can be handled by irqdomain.
