ARM: mmp: add support for MMP3 SoC
Similar to MMP2, which this patch is based on. Known differencies from MMP2 are: * Two PJ4B cores instead of one PJ4 * Tauros 3 L2 cache controller instead of Tauros 2 * A GIC interrupt controller optionally used instead of the MMP one * A TWD local timer * Different USB2 PHY * A USB3 SS controller * More interrupt muxes Hard to tell what else is different, because documentation is not available.
