hw/pci-host: Add emulation of Marvell MV64361 PPC system controller

Browse source 
The Marvell Discovery II aka. MV64361 is a PowerPC system controller
chip that is used on the pegasos2 PPC board. This adds emulation of it
that models the device enough to boot guests on this board. The
mv643xx.h header with register definitions is taken from Linux 4.15.10
only fixing white space errors, removing not needed parts and changing
formatting for QEMU coding style.
