I'd rather create the Gsp structure already, move the code to Gsp::new() and
return an impl PinInit<Self, Error>. If you don't want to store any of the
object instances you create above yet, you can just stuff all the code into an
initializer code block, as you do in the next patch with
gfw::wait_gfw_boot_completion().
