Hi,

Allwinner H6 is a new SoC with Cortex-A53 cores from Allwinner, with its
memory map fully reworked and some high-speed peripherals (PCIe, USB
3.0) introduced.

This commit adds the basical DTSI file of it, including the clock
support and UART support.
Checked the MMIO addresses and the interrupt numbers against the manual.
