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.

Changes in v2:
- Add APB1 clock as PIO's APB clock.
- Switched to SPDX license identifier.

Checked the MMIO addresses and the interrupt numbers against the manual.
