Subject: [PATCH] ARM: dts: overlays: Add cs_pin and irq_gpio overrides to
 AD7124 overlays

Ensure all AD7124-related overlays expose consistent __overrides__ for
both the SPI chip-select and IRQ GPIO pins:

- rpi-ad7124: add cs_pin (irq_gpio was already present)
- rpi-cn0554: add __overrides__ with cs_pin and irq_gpio
- rpi-cn0556: add __overrides__ with cs_pin and irq_gpio
- rpi-cn0508: add cs_pin and irq_gpio to existing __overrides__
