Subject: [PATCH v3 1/4] arm64: dts: ti: k3-j722s-evm: Enable "serdes_wiz0" and "serdes_wiz1"

In preparation for disabling "serdes_wiz0" and "serdes_wiz1" device-tree
nodes in the SoC file, enable them in the board file. The motivation for
this change is that of following the existing convention of disabling
nodes in the SoC file and only enabling the required ones in the board
file.
