[PATCH] ppc64: fix enable_surveillance() for power5
On some platforms (notably power5) you can't enable surveillance
(firmware/service processor watchdog) from the kernel - you have to do
it in the firmware.
This patch changes enable_surveillance() to make the message that is
printed in this situation more informative. Additionaly, the rtas_call
was changed to rtas_set_indicator so as to avoid having to handle
RTAS_BUSY returns.
