realtek: rtl931x: Support enable/disable SMI Polling for SerDes ports
During PHY matching, the SMI polling must be disabled to avoid conflicts
during the complex detection routine. Only after this finished, SMI polling
is allowed again.
This was implemented for all realtek families besides RTL931x.
