arm64: dts: exynos: Add initial support for exynos8895 SoC

Exynos 8895 SoC is an ARMv8 mobile SoC found in the Samsung Galaxy
S8 (dreamlte), S8 Plus (dream2lte), Note 8 (greatlte) and the Meizu
15 Plus (m1891). 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.
