Not all ipmi related functions check for a valid backend before
attempting to use it. Under normal circumstances this should not
happen as the platform should always register an ipmi backend. However
a system should be able to boot without a functional ipmi backend,
which is sometimes the case during system bringup.
This patch adds presence checks for an ipmi backend before attempting
to use it, thus allowing a system with a non-functional backend to
boot without ipmi.

Currently the only functions we have for initialising ipmi messages
with the correct values also allocate memory for the message. In some
cases we want to reuse previously allocated messages to avoid
continually freeing/allocating memory.
This patch introduces a function which (re)initialises a previously
allocated message and converts existing instances of this behaviour
over to the new function.

This is probably not the best collection of things in the world,
but it means that opal.h is much closer to being directly usable
by an OS.
This triggers a bunch of #include fixes throughout the tree.

The FRU data format limits string length to 31 characters. Currently
we truncate the version string as required but leave the redundant
(because it's included in the product name field) "skiboot-" at the
start of the version.
This patch removes the redundant prefix allowing more of the actual
version string to be stored. It also fixes a bug which caused the last
character of a 31 character version string to be overwritten as well
as a rather embarrassing off-by-one buffer overflow.
Note that 31 characters should be enough to store the complete version
string for any release builds.

This patch adds basic support for populating some fru data. Currently
we only support adding the skiboot version number to the product
information area.
