phy: ti: j721e-wiz: Add support for WIZ module present in TI J721E SoC

Browse Source 
Add support for WIZ module present in TI's J721E SoC. WIZ is a SERDES
wrapper used to configure some of the input signals to the SERDES. It is
used with both Sierra(16G) and Torrent(10G) SERDES. This driver configures
three clock selects (pll0, pll1, dig) and supports resets for each of the
lanes.

This is an adaptation of the linux driver.
