rockchip: back-to-bootrom: allow passing a cmd to the bootrom
The BROM supports forcing it to enter download-mode, if an appropriate
result/cmd-word is returned to it. There already is a series to
support this in review, so this prepares the (newly C-version) of the
back-to-bootrom code to accept a cmd to passed on to the BROM.
All the existing call-sites are adjusted to match the changed function
signature.
