[PATCH] olpc: fix model detection without OFW

Harvey's endianness patch (e51a1ac2dfca9ad869471e88f828281db7e810c0)
breaks model comparison on OLPC; the value 0xc2 needs to be scaled
up by olpc_board(). The pre-patch version was wrong, but accidentally
worked anyway (big-endian 0xc2 is big enough to satisfy all other
board revisions, but little endian 0xc2 is not).
