Provide proper support for SPI on Arm SystemReady IR devices (imx8 and nvidia orin)

Al Stone requested to merge ahs3/edge-stream-9:imx8/spi-v1 into main 
Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=2071848
Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=2122415
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.
