Subject: [PATCH 7/8] ARM: shmobile: r8a73a4 dtsi: Add Bus State Controller node

Add a node for the Bus State Controller (BSC) on r8a73a4, to which
multiple external devices can be connected.

The BSC is driven by the ZB clock, and located in PM domain C4.
A reference to the latter will be added later.
