[PATCH] PPC64: use c99 initializers

Hi Andrew,

This patch is just more clean up in the ppc64 arch.  It uses c99
initializers for various iSeries structures that are used to pass
information to the hypervisor.  Also itLpNaca is not used by any code that
could be in a module, so don't export it.

Built and booted.

Signed-off-by: Stephen Rothwell <sfr at canb.auug.org.au>

Please apply.

P.S. for the StudlyCaps brigade, changing these is on my To Do list. :-)
