[PATCH 5/6] staging: dpaa2-ethsw: store version information of the DPSW object

[Ioana Ciornei <ioana.ciornei@xxxxxxx>]

Store the major and minor versions of the DPSW object in the ethsw
structure. This will be used in a subsequent patch to make sure some
commands are only called on the appropriate version of object.
