This series adds support for DFU in SPL for rockchip rk3588 on rock5b board.
Namely, when SPL is loaded via rockusb (thus via USB), having the `same-as-spl` boot order item, after having detected that it was loaded from USB, it will lookup the gadget USB node in DT and boot via DFU.
Some changes were required namely: - DFU needs environment, hence adding environment variables into DFU - added bootph-all to nodes such that they are available in SPL - insert gadget into boot order
I had to port one patch for DWC3 from Linux, and include in this series the patches that are floating from Venkatesh that fixup the DWC3 (https://marc.info/?l=u-boot&m=168351919807081&w=2 )
I know that Marek NAKed them and I am fine with it, I am not trying to sneak in any patches, they are not to be merged, also this patch `usb: dwc3: Increase DWC3 controller halt timeout` is in the same bucket so Marek you can NAK this one as well, no problem, I am just sending out all the series so maybe the rockchip part for the gadget can be picked up and if people want to use the DFU SPL gadget can also manually pick the DWC3 patches. The branch with all the patches is available here :

Thanks!
Changes in v2: - rebased on latest upstream which caused a change in the config patch.
