Merge patch series "Convert extension support to UCLASS and adds its support to boot flows"

Kory Maincent (TI.com) <kory.maincent@bootlin.com> says:

This series converts the extension board framework to use UCLASS as
requested by Simon Glass, then adds extension support to pxe_utils
and bootmeth_efi (not tested) to enable extension boards devicetree load
in the standard boot process.

I can't test the imx8 extension scan enabled by the
imx8mm-cl-iot-gate_defconfig as I don't have this board.
I also can't test the efi bootmeth change as I don't have such board.
