Merge https://gitlab.denx.de/u-boot/custodians/u-boot-usb

- Assorted gadget changes including:
  - dfu: Fix handling of UBI partitions in MTD backend
  - gadget: f_thor: fix wrong file size cast
  - Extend cmd: bcb
  - Fixes for fastboot and rockchip gadgets
  - dfu: Add SCRIPT and SKIP entities
  - dfu/thor: Add `dfu_alt_info` reinitialization from flashed script
  - u-boot: Reduce size of u-boot as usbd_device_* arrays are not exported
