Subject[PATCH v2 4/6] Sysace: minor rework and cleanup changes
From: Grant Likely <grant.likely@secretlab.ca>

Miscellanious rework to the sysace driver; Not critical, but makes the
subsequent addition of the of_platform bus binding a wee bit cleaner

Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
