This patch adds the workaround for the errata#2. The KSZ9031 phy
125MHz reference clock jitter is to high if the phy is configured as
slave. This will cause errors if a application uses the clock as
MAC reference clock. The workaround is to configure the phy as master.
v2:
- add more code and dt-binding comments
- delete unnecessary local variables
- add error handling
v1:
- initial commit

I forgot to set the thread option. I will resend with thread option
enabled.
