Add support for input switches SW1-3 on the Renesas RZ/A1 RSK+RZA1
development board.
Note that this uses the IRQ interrupts, as the RZ/A1 GPIO controller
does not include interrupt support.

Describe the remaining 3 LEDs, which are driven by the first CAT9554
port expander.
Drop the superfluous status property from the leds node while at it.

Enable the I2C bus, and add the following devices:
- Two CAT9554 port expanders (8 GPIOs, interrupt not wired by
default),
- R1EX24016ASAS0A EEPROM.
The bus also contains a MAX9856 Audio Codec, which is not yet supported.
All devices (incl. the audio codec) are documented to support an I2C bus
running at 400 kHz.
Pinctrl is based on the RZ/A BSP.
