Change the way PHY devices are named upon creation. This commit replaces
sequentialy numbered "/dev/phy%d" with "/dev/mdio%d-phy%02x". This way
it is significanlty easier to identify which PHY in real-life (e.g. on a
schematic) corresponds to which device in /dev.
Also, replace asprintf with xasprintf to provide some form of memory
allocation failure checking.
