Tony Lindgren e5a49c1e3b net: cpsw: Add a minimal cpsw-common module for shared code
Looks like davinci_emac and cpsw can share some code although the
device registers have a different layout.

At least the code for getting the MAC address using syscon can
be shared by passing the register offset. Let's start with that
and set up a minimal shared cpsw-shared.c.
