[PATCH v2 0/2] arm64: dts: qcom: monaco-arduino-monza: Prepare JHAT 40-pin connector for HAT overlays

[Srinivas Kandagatla]

The Arduino VENTUNO Q board exposes a 40-pin JHAT connector that is
pin-compatible with the Raspberry Pi HAT specification. These two
patches lay the DT groundwork so that HAT accessories can be wired
up via overlays:

 - enable I2C0 and SPI3 on the JHAT connector and add the i2c0/spi0
   aliases, covering accessories such as the Pimoroni Automation HAT
   [1] which uses I2C for its on-board ADS1015 ADC and SN3218 LED
   driver;
 - add a label to the sound node so audio HAT overlays can extend it.

Changes in v2:
 - dropped patch 3 (Waveshare WM8960 Audio HAT overlay); needs more
   work
 - picked up Reviewed-by tags from Loic Poulain, Dmitry Baryshkov and
   Konrad Dybcio on patch 1
 - picked up Reviewed-by tag from Dmitry Baryshkov on patch 2
 - rebased on b-next-20261028
