Change all files in common/ to use CMD_RET_USAGE instead of calling
cmd_usage() directly. I'm not completely sure about this patch since
the code since impact is small (100 byte or so on ARM) and it might
need splitting into smaller patches. But for now here it is.

The new mdio command doesn't have all of the features of the mii
command, but it provides the necessary read/write primitives, and allows
users to interact with 10G PHYs, and other PHYs which use Clause 45 of
802.3. This means that the mdio command requires a "Device Address"
argument, though for clause 22 PHYs, the argument can be "-".
