Subject: [PATCH] csiostor:T5 Firmware fix and cleanup.
This patch fix is to use default firmware configuration files
present in the adapter incase if not available in standard
/lib/firmware/* dir. Additional cleanup is done to reuse flash
related defines from cxgb4 header file.
Please apply over net-next since it depends on previous commit.
