OPAL/IBM calls it CAPI and Linux calls it CXL because CAPI was taken.
In order to have opal.h match between firmware and Linux, we're going
to just deal with one call used in a place be CAPI rather than CXL to
match what's in firmware.

To further the cause of syncing opal.h between firmware and linux,
move the function prototypes that were in opal.h out to opal-api.h
and fix the associated includes.
There are still a few places where opal.h is adequate.

Add the missing pieces in order to enable SECCOMP_FILTER on PowerPC

Testing has been pursued using libseccomp with the latest ppc support patches

untested.

The secure_computing_strict will just force the kernel to panic on
secure_computing failure. Once SECCOMP_FILTER support is enabled in the kernel,
syscalls can be denied without system failure.
