realtek: pcs: rtl931x: drop sequence in favor of function

Browse source 
Drop a register write sequence from the USXGMII setup for RTL931x in
favor of using a function that is already present. From the name, the
function initializes LEQ DFE. Though it's not yet clear what it exactly
does, this is already better then having a sequence with no explanation
somewhere in the code.

Apparently, when this code was added, the function wasn't present
but it's content was just added here as single usage.
