[PATCH v3] board: rpi: Enable capsule updates

[Ilias Apalodimas]

Since RPI works well using EFI and has no size limitations with regards
to U-Boot, add the needed structures to support capsule updates.

While at it update the most commonly used defconfigs and include capsule
support and U-Boot commands needed by EFI

This needs to be applied *after*
https://lore.kernel.org/u-boot/20240830-b4-dynamic-uuid-v8-0-79b31b199bee@linaro.org/

I managed to test this on rpi5 and works
Changes since v2:
- Add missing DFU options for rpi3 and rpi defconfigs

Changes since v1:
- Remove a redundant function definition
- Add the required Kconfig options in more defconfigs
- add my SoB which was missing...
