[PATCH/RFC 1/3] ARM: shmobile: sh73a0 dtsi: Add Bus State Controller node

[Geert Uytterhoeven]

Add a node for the Bus State Controller (BSC) on sh73a0, to which
multiple external devices can be connected.

The BSC is driven by the ZB clock, and located in PM domain A4S.

For now no device tree bindings have been defined yet. All of its
properties follow standard conventions.
