[PATCH v4] ARM: dts: renesas: r9a06g032-rzn1d400-db: describe debug LEDs

[Wolfram Sang <wsa+renesas@xxxxxxxxxxxxxxxxxxxx>]

Enable the debug LEDs connected via the I2C GPIO extender.

Signed-off-by: Wolfram Sang <wsa+renesas@xxxxxxxxxxxxxxxxxxxx>

Changes since v3:
- decided on LED_FUNCTION_DEBUG after discussion with LED maintainers
- dropped "keep" default since it did not work reliably with the GPIO
  extender and no bandwidth to debug it
- rebased to linux-next
