Subject: [PATCH 3/4] arm64: dts: ti: k3-j721s2-main: Make the "scm_conf" node a "simple-bus"

The "scm_conf" bus need not be "syscon". Now that we have "pcie*_ctrl"
child nodes for "ti,syscon-pcie-ctrl" property in "pcie" nodes, change
"scm_conf" node to "simple-bus".
Also remove "reg" property as it is not needed by "simple-bus".
