Subject: [PATCH 1/2] MIPS: cavium-octeon: cvmx-helper-board: print unknown board warning only once

When booting a new board for the first time, the console is flooded with
"Unknown board" messages. This is not really helpful. Board type is not
going to change after the boot, so it's sufficient to print the warning
only once.
