boot: Remove impl of Info for Linux Boot Protocol

The Linux Boot Protocol is no longer supported for starting RVH and as
such there is no need to implemement that trait.

In this case the trait was also being overloaded for access to some code
for booting *with* the Linux Boot Protocol and so those functions are
now directly included in `boot::Params`.
