[PATCH v2 1/1] arm64: dts: imx95-var-dart-sonata: add CAN controller

[Stefano Radaelli]

From: Stefano Radaelli <stefano.r at variscite.com>

Add the MCP251xFD CAN controller connected to LPSPI7 chip select 1 on
the Sonata carrier board.

Add the second SPI chip select GPIO and describe the CAN interrupt and
pinctrl configuration.
