A few headers neglect to include headers they need. They compile only
if something else includes the required header(s) first. Fix that.

The SBE (Self Boot Engine) are on-chip microcontrollers that perform
early boot steps, as well as provide some runtime facilities (e.g.,
timer, secure register access, MPIPL). The latter facilities are
accessed mostly via a message system called SBEFIFO.
This driver provides initial emulation for the SBE runtime registers
and a very basic SBEFIFO implementation that provides the timer
command. This covers the basic SBE behaviour expected by skiboot when
booting.
