realtek: pcs: rtl931x: drop RX channel resets during USXGMII config

The mode configuration calls LEQ/DFE reset and RX reset before doing
USXGMII configuration. Though the SDK does that similar, these calls are
actually unneeded because essentially the same is executed later again
in the attachment configuration. This is also the place where it
rather belongs. Thus, drop those calls in mode configuration.
