[net,v2,0/2] net: phy: Fix potential string cut when using PHY_ID_FMT

Message

The agreement and also PHY_MAX_ADDR limit suggests that the PHY id can't occupy
more than 2 hex digits. In some cases GCC complains about potential string cut.
Avoid that by limiting specifier to print only 2 hex digits (patch 1).
With that, fix the ASIX driver that triggers GCC and use agreed + 3 in the size
of the phy_name (patch 2).

In v2:
- added first patch
- added a conditional to the ASIX driver (Andrew)
