irqchip fixes for 5.12, take #1

- More compatible strings for the Ingenic irqchip (introducing the
  JZ4760B SoC)
- Select GENERIC_IRQ_MULTI_HANDLER on the ARM ep93xx platform
- Drop all GENERIC_IRQ_MULTI_HANDLER selections from the irqchip
  Kconfig, now relying on the architecture to get it right
- Drop the debugfs_file field from struct irq_domain, now that
  debugfs can track things on its own
irqchip/ingenic: Add support for the JZ4760

Add support for the interrupt controller found in the JZ4760 SoC, which
works exactly like the one in the JZ4770.
