hw/net/lan9118_phy: Reuse in imx_fec and consolidate implementations

imx_fec models the same PHY as lan9118_phy. The code is almost the same with
imx_fec having more logging and tracing. Merge these improvements into
lan9118_phy and reuse in imx_fec to fix the code duplication.

Some migration state how resides in the new device model which breaks migration
compatibility for the following machines:
* imx25-pdk
* sabrelite
* mcimx7d-sabre
* mcimx6ul-evk
