net: stmmac: consolidate version reading and validation

Browse source

There is no need to read the version register twice, once in
stmmac_get_id() and then again in stmmac_get_dev_id(). Consolidate
this into stmmac_get_version() and pass each of these this value.

As both functions unnecessarily issue the same warning for a zero
register value, also move this into stmmac_get_version().
