Add minimal support for that SoC, including: - All 8 cores via PSCI - ChipID - Generic ARMV8 Timer - Enumarate all pinctrl nodes The devices using this SoC suffer from an issue caused by the stock Samsung bootloader, as it doesn't configure CNTFRQ_EL0. Hence it's needed to hardcode the adequate frequency in the timer node, otherwise the kernel panics. Further platform support will be added over time.
