Nathan Lynch edc72ac4a0 powerpc/pseries: Check for GIQ indicator before calling set-indicator
Since "Factor out cpu joining/unjoining the GIQ"
(b4963255ad) the WARN_ON in
xics_set_cpu_giq() is being triggered during boot on JS20 because the
GIQ indicator is not available on that platform.  While the warning is
harmless and the system runs normally, it's nicer to check for the
existence of the indicator before trying to manipulate it.

Implement rtas_indicator_present(), which searches the
/rtas/rtas-indicators property for the given indicator token, and use
this function in xics_set_cpu_giq().

Also use a WARN statement in xics_set_cpu_giq to get better
information on failure.
