Peng Fan 6d97dc10a8 imx: clock support enet2 anatop clock support 
To i.MX6SX/UL, two ethernet interfaces are supported.
Add ENET2 clock support:
1. Introduce a new input parameter "fec_id", only 0 and 1 are allowed.
   To value 1, only i.MX6SX/UL can pass the check.
2. Modify board code who use this api to follow new api prototype.
