The LS1021A allows inverting the polarity of six interrupt lines IRQ[0:5] via the scfg_intpcr register, effectively allowing IRQ_TYPE_LEVEL_LOW and IRQ_TYPE_EDGE_FALLING for those. We just need to check the type, set the relevant bit in INTPCR accordingly, and fixup the type argument before calling the GIC's irq_set_type. In fact, the power-on-reset value of the INTPCR register on the LS1021A is so that all six lines have their polarity inverted. Hence any hardware connected to those lines is unusable without this: If the line is indeed active low, the generic GIC code will reject an irq spec with IRQ_TYPE_LEVEL_LOW, while if the line is active high, we must obviously disable the polarity inversion (writing 0 to the relevant bit) before unmasking the interrupt. Some other Layerscape SOCs (LS1043A, LS1046A) have a similar feature, just with a different number of external interrupt lines (and a different POR value for the INTPCR register). This driver should be prepared for supporting those by properly filling out the device tree node. I have the reference manuals for all three boards, but I've only tested the driver on an LS1021A. Unfortunately, the Kconfig symbol ARCH_LAYERSCAPE only exists on arm64, so do as is done for irq-ls-scfg-msi.c: introduce a new symbol which is set when either ARCH_LAYERSCAPE or SOC_LS1021A is set.
