atl1c: Add support for Atheros AR8152 and AR8152

AR8151 is a Gigabit Ethernet device. AR8152 devices are
Fast Ethernet devices, there are two revisions, a 1.0
and a 2.0 revision.

This has been tested against these devices:

Driver	Model-name	vendor:device	Type
atl1c 	AR8131		1969:1063	Gigabit Ethernet
atl1c	AR8132		1969:1062	Fast Ethernet
atl1c	AR8151(v1.0)	1969:1073	Gigabit Ethernet
atl1c	AR8152(v1.1)	1969:2060	Fast Ethernet

This device has no hardware available yet so it goes untested,
but it should work:

atl1c	AR8152(v2.0)	1969:2062	Fast Ethernet
