In the sbe_retry_handler code we have two methods we can use to restart
the sbe. They are restarting the cfam boot sequence (start_cbs HWP) and
performing a hw reset on the PPE (hreset HWP). We use start_cbs if there
are issues with initial power on of the slave proc's SBE because we will
not lose any state info (fabric isn't up yet). During runtime we will want
to use the hreset HWP to recover the SBE. Hreset is handy because it will
not force a reboot of the entire proc chip, so the fabric can stay up while
we reset the PPE in the SBE. This commit implements the code path for the
hreset HWP in the sbe_retry_handler. In addition this commit enables calls to
the sbe_retry_handler in rt_fwnotify's sbeAttemptRecovery function which
handles PHYP requests to recover the SBE.
(Also some small typos in related code fixed)

Previously the sbe_retry_handler had logic and wording that
assumed that it was being used to tell if the slave sbe booted or not.
However this code has many more use cases then that. Also there was some
indirect recursion that made the code hard to follow. With this refactor
the code should be easier to follow and the vocabulary used should be more
generic.

We want to move the sbe_retry_handler.C and other files
associated with it to a common directory and makefile.
