arm64: dts: exynos: add initial support for exynos2200 SoC

Exynos 2200 SoC is an ARMv8 mobile SoC found in the Samsung Galaxy S22
(r0s), S22+ (g0s), S22 Ultra (b0s) Add minimal support for that SoC,
including psci, pmu, chipid, architecture timer and mct, pinctrl,
clocks and usb.

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.
