sparc64: retry domain service registration MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit

Domain service registration intermittently fails. Though using “reliable"
LDC communication, this only guarantees the data, not delivery. Analysis
indicated a timing issue that varies between boots. LDOM domain service
architecture is now sufficiently complicated that packets (domain service
registration requests in this case) do apparently get lost, the symptoms
being receiving neither an ACK or a NACK on the initial service registration
request.

This patch uses a timer and retries with delay up to N (currently 5) times
any requests that went unacknowledged, positively or negatively, before
reporting a failed registration attempt. Using timer with callback allows early
boot to progress as normal versus spinning in a loop. Also clean up of
./script/checkpatch.pl warnings and errors in ds.c.
