[PowerPC64LE] Fix RTAS LE calls in pseries.

Similar to OPAL calls, switch to big endian to do calls to RTAS.

(Missed this one when I was doing the bulk commit of PowerPC64LE support.)

sys/powerpc: further adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

Merge sync of head

Merge from HEAD

Merge ^/head r277327 through r277718.

MFhead @ r277555

Allow use of a pre-instantiated RTAS as well as a self-instantiated one. This
lets the kernel boot on RTAS-based systems by being kexec'ed from Linux.

Make RTAS calls, which call setfault() to recover from machine checks,
preserve any existing fault buffer. RTAS calls are meant to be safe from
interrupt context (and are indeed used there to implement the xics PIC
drvier). Without this, calling into RTAS in interrupt context would have
the effect of clearing any existing onfault state of the interrupted
thread, potentially leading to a panic.
