[PATCH v1 01/11] arm64: dts: freescale: imx8mm-verdin: Add SPI alias

[Francesco Dolcini <francesco@dolcini.it>]

From: Francesco Dolcini <francesco.dolcini@toradex.com>

The Verdin family pinout defines the SoM interfaces and their
numbering, SPI_1 being the SPI bus available to the carrier board,
implemented by ecspi2 on Verdin iMX8MM.

imx8mm.dtsi numbers ecspi2 as spi1, so the Linux bus number in sysfs
and the spidev name do not match the Verdin interface. Add a spi0
alias in the SoM dtsi and delete the inherited spi1, so ecspi2 is
bus 0, zero-based with SPI_1 being spi0, and carries a single alias.
ecspi3, internal to the SoM with the CAN controller and the TPM, keeps
the spi2 alias inherited from the SoC.
