Tested: This set has been sanity tested via simple boot tests on imx8mm
and Jetson Xavier systems, along with the CI loop. NB: this
patch set is insufficient to boot Orin by itself. Further work
to develop tests with spidev and/or spidev_test is on-going.
Update drivers/spi to about Linux 6.0, paying special attention
to the imx8 and orin platforms. Update spidev as well in order
to assist with QE. Note that there are a large number of SPI
devices not currently supported that may require work if they
get requested.
