[PATCH v2 0/5] Resync BeagleBone dtbs, add SanCloud BBE support & minor fixups

This updated patch series takes the approach of copying the device trees
for the BeagleBone Black, BeagleBone Green & BeagleBone enhanced from
the latest stable Linux kernel (v5.13.1). To support this we also need
to port over a couple of changes to the relevant dt-bindings headers.
I considered also copying the newer versions of am33xx*.dtsi but this
resulted in significant churn and incompatibility with some of the other
devicetrees in the u-boot tree.

With the new device trees in place we enable GbE phy support and fix the
DTB ordering in the am335x evm defconfig. These two patches are
unchanged from the v1 series previously sent to the list.

With these changes applied, Ethernet works on the SanCloud BBE in
u-boot.

These changes have been tested on both a SanCloud BBE and on a
BeagleBone Black. In both cases it was confirmed that Ethernet worked in
u-boot and that we could successfully boot a Linux kernel & rootfs built
with Yocto Project.
