SSI-87: firmware: imx: Add APIs required for secvio
The Security Violation module requires SC API for the SECO, RM, MISC
and IRQ.
This patch does:
- imx-scu-irq: Allow reuse of imx_scu_irq_get_status
- seco:
- Add imx_sc_seco_secvio_enable
- Add imx_sc_seco_secvio_config
- Add imx_sc_seco_secvio_dgo_config
