rk3399: add ability to configure SPI5

This defines mux settings for the GPIO bank responsible for SPI
    interface #5.

BRANCH=none
    BUG=chrome-os-partner:51537
    TEST=with the rest of the patches applied it is possible to
         communicate with the EC on gru: pressing Ctrl-U during boot
         allows to start Chrome OS from the SD card.
