Subject[PATCH v6 2/2] staging: fsl-mc: Move irqchip code out of staging
Date
Now that the fsl-mc bus core infrastructure is out of staging, the
remaining irqchip glue code used (irq-gic-v3-its-fsl-mc-msi.c) goes
to drivers/irqchip.

Create new Kconfig option for irqchip code that depends on
FSL_MC_BUS and ARM_GIC_V3_ITS. This ensures irqchip code only
gets built on ARM64 platforms. We can now remove #ifdef
GENERIC_MSI_DOMAIN_OPS as it was only needed for x86.
