This creates a model for PolarFire SoC IOSCB [1] module. It actually
contains lots of sub-modules like various PLLs to control different
peripherals. Only the mininum capabilities are emulated to make the
HSS DDR memory initialization codes happy. Lots of sub-modules are
created as an unimplemented devices.
