[U-Boot] [PATCH v2] fastboot: Remove "bootloader-version" variable

[Sam Protsenko]

As per [1], there is no such fastboot variable as "bootloader-version".
Only "version-bootloader" is supported. Let's reflect this and not
confuse users further.

[1] https://android.googlesource.com/platform/system/core/+/refs/tags/android-q-preview-4/fastboot/README.md

Fixes: 3aab70afc531d1 ("usb/gadget: add the fastboot gadget")

Changes in v2:
  - add "Fixes:" tag
  - use fixed link (tag instead of branch)
  - remove section in link (which may be changed in future)
  - fixed bootloader version in doc (to not confuse the user)
