arm: dts: Resync dts for BeagleBone and derivatives
Sync BeagleBone dts files & TPS dtsi files with Linux v5.17 and include
the SanCloud BBE Extended WiFi dts added in v5.18-rc1. Also pull in
changes to am33xx-l4.dtsi needed to support the BeagleBone Blue.
The change to use the cpsw switch driver (commit c477358e66a3 in Linux)
is excluded from the sync as u-boot does not recognise the new
compatible string.
