hw/net/lan9118: Extract lan9118_phy

Browse source 
A very similar implementation of the same device exists in imx_fec. Prepare for
a common implementation by extracting a device model into its own files.

Some migration state has been moved into the new device model which breaks
migration compatibility for the following machines:
* smdkc210
* realview-*
* vexpress-*
* kzm
* mps2-*

While breaking migration ABI, fix the size of the MII registers to be 16 bit,
as defined by IEEE 802.3u.
