[PATCH v1 2/3] arm64: dts: ti: k3-am62p-verdin: Add SPI alias

[Francesco Dolcini]

From: Francesco Dolcini <francesco.dolcini@xxxxxxxxxxx>

The Verdin family pinout defines the SoM interfaces and their
numbering, SPI_1 being the SPI bus on the SODIMM connector, implemented
by main_spi1 on Verdin AM62P.

Without an alias the Linux SPI bus number is assigned dynamically and
depends on probe order against main_spi0. Add a spi0 alias so the bus
number in sysfs and the spidev name follow the Verdin interface
numbering, zero-based with SPI_1 being spi0. main_spi0 is a
module-specific SPI on reserved SODIMM pins with the TPM as its only
device. It is not part of the Verdin pinout and gets no alias.
