    mgb: Update man page wrt state of the driver
    
    Be explicit that the driver has caveats and limitations, and remove the
    note about not being connected to the build: I plan to connect it soon.
    (Also the note serves no real purpose in a man page that is not
    installed.)

    (cherry picked from commit 667ea7385d9ce45c376260e9c2c893c51514e25e)
