The version information is at the bit31 ~ bit16 in the VERID
register, so need to right shift 16bit to get it, otherwise
the result of comparison "sai->verid.version >= 0x0301" is
wrong.

I would put the version in one line, but probably is easier to read this
way.
Also, please explain, in commit message, what and from where is 0x0301 -
might worth adding a macro for this, in another commit, of course.
Otherwise,
