irqchip: Add LoongArch CPU interrupt controller support
LoongArch CPUINTC stands for CSR.ECFG/CSR.ESTAT and related interrupt controller that described in Section 7.4 of "LoongArch Reference Manual, Vol 1". For more information please refer Documentation/loongarch/irq- chip-model.rst. LoongArch CPUINTC has 13 interrupt sources: SWI0~1, HWI0~7, IPI, TI (Timer) and PCOV (PMC). IRQ mappings of HWI0~7 are configurable (can be created from DT/ACPI), but IPI, TI (Timer) and PCOV (PMC) are hardcoded bits, so we expose the fwnode_handle to map them, and get mapped irq by irq_create_mapping when using them.
