Felix Fietkau	736419452b	cns3xxx: fix shared PCI interrupt mapping ... This patch originally failed to combine INTA/B/C/D onto a single ARM CPU interrupt. Instead, it mapped INTA/B/C and excluded D. This patch corrects the issue by mapping all four interrupts to the single ARM CPU interrupt. The original intent of the patch still holds as the newer PCB take advantage of isolated interrupts. This fix only applies to older PCB's that do not route INTA/B/C/D to unique external ARM CPU interrupts.

Felix Fietkau	1839d1b912	cns3xxx: support isolated PCI interrupts on newer Laguna PCBs ... The cns3xxx uses irq61 for pcie0_intr which in the case of a PCIe-to-PCI bridge ends up combining INTA/B/C/D on a single ARM CPU interrupt. This is not optimal when you have multiple cores. To overcome this limitation an enhancement was made on newer Laguna PCB's that support miniPCI cards to route the INTA/B/C/D signals to unique external ARM CPU interrupts which can help balance CPU core utilization and in some cases increase overall system performance or responsiveness.
