realtek: fix SFP support on Engenius EWS2910P
Some checks are pending
Build Kernel / Build all affected Kernels (push) Waiting to run
Details

Browse source 
EWS2910P has two SFP slots of which only one was fully supported so far.
The issue so far was that both SFP slots share the same I2C SCL line but
neither the kernel nor any downstream driver was able to deal with this.

Thus, only one SFP slot was completely working (with detection etc.) but
the other one had to be enabled manually. Networking was functional in
both though.

Since acd7ecc9ed we have a driver which is able to deal with that. Thus,
we can fix the SFP support for this device.
