ARM: imx: move irq_domain_add_legacy call into tzic driver

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.
