Subject: [PATCH v2 3/3] ARM: dts: vf610: add Miscellaneous System Control Module (MSCM)

Add the Miscellaneous System Control Module (MSCM) to the base
device tree for Vybrid SoCs. This module contains the peripheral
interrupt router, which is handling the routing of the interrupts
between the two cores.
