The driver tests for the hardware revision being newer than 3.1 with (sai->verid.major >= 3 && sai->verid.minor >= 1). The result is obviously wrong for hardware revision 4.0. Fix this by storing the full version in a single variable and comparing to that one. No practical change at the moment as there is no 4.0 ip version currently.
