ASoC: fsl_sai: store full version instead of major/minor

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.
