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 v3:
*) Fix Rob's comments on dt bindings
-> Add properties to be added in WIZ child nodes to binding
-> Use '-' rather than '_' in node names

Changes from v2:
*) Deprecate "phy_clk" binding
*) Fix Rob's comment on dt bindings
-> Include BSD-2-Clause license identifier
-> drop "oneOf" and "items" for compatible
-> Fixed "num-lanes" to include only scalar keywords
-> Change to 32-bit address space for child nodes
*) Rename cmn_refclk/cmn_refclk1 to cmn_refclk_dig_div/
cmn_refclk1_dig_div

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