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.
