PHY: Add support for SERDES in TI's J721E SoC

TI's J721E SoC uses Cadence Sierra SERDES for USB, PCIe and SGMII.
TI has a wrapper named WIZ to control input signals to Sierra and
Torrent SERDES.

This patch series:
 1) Add support to WIZ module present in TI's J721E SoC
 2) Adapt Cadence Sierra PHY driver to be used for J721E SoC

Changes from v1:
 *) Change the dt binding Documentation of WIZ wrapper to YAML format
 *) Fix an issue in Sierra while doimg rmmod
