x86, olpc: fix model detection without OFW
Impact: fix "garbled display, laptop is unusable" bug
Commit e51a1ac2dfca9ad869471e88f828281db7e810c0 ("x86, olpc: fix endian
bug in openfirmware workaround") 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).
