realtek: fix SFP support on Plasma Cloud ESX28/PSX28

Like other RTL931x devices, the Plasma Cloud ESX28 and PSX28 also have
inverted polarity on the SerDes which drive the SFP ports. Commonly,
those always seem to have inverted TX polarity. This was missing from
when the devices were added at which time SFP on RTL931x wasn't working
at all yet. Add the polarity to the DTS now.

Verified on Plasma Cloud PSX28.
