arm64: dts: ti: k3-j721s2: Make MAIN domain system control bus a simple-bus

This node describes a memory address range containing several sub-regions
with control registers for various IP in the MAIN domain of this SoC. It
was described as a "ti,j721e-system-controller" but this is a J721S2 SoC
with is not compatible with the system controller region found in J721e.

No project consuming this DT has been found that makes use of the syscon
compatible for this region, to prevent any from using this node like a
generic syscon region in the future, make this a normal simple-bus as
it should have been from the start.
