mailbox: zynqmp-ipi: Fix SGI cleanup on unbind
In the Linux kernel, the following vulnerability has been resolved: mailbox: zynqmp-ipi: Fix SGI cleanup on unbind The driver incorrectly determines SGI vs SPI interrupts by checking IRQ number < 16, which fails with dynamic IRQ allocation. During unbind, this causes improper SGI cleanup leading to kernel crash. Add explicit irq_type field to pdata for reliable identification of SGI interrupts (type-2) and only clean up SGI resources when appropriate.
