Nava kishore Manne 7eb61caf45 phy: zynqmp: keep SERDES scrambler and 8b/10b enabled for USB ...

USB Gen1 requires scrambling and 8b/10b encoding to be performed in the
physical layer. Do not bypass PHY-side scrambler or encoder/decoder for
USB operation, as mandated by the USB 3.x specification.

Scrambler and 8b/10b bypass remain restricted to SATA and SGMII
modes, where encoding is handled in the controller.
