[PATCH v3 07/10] arm64: dts: add Allwinner A64 SoC .dtsi

[Andre Przywara <andre.przywara@arm.com>]

The Allwinner A64 SoC is a low-cost chip with 4 ARM Cortex-A53 cores
and the typical tablet / TV box peripherals.
The SoC is based on the (32-bit) Allwinner H3 chip, sharing most of
the peripherals and the memory map.
Although the cores are proper 64-bit ones, the whole SoC is actually
limited to 4GB (including all the supported DRAM), so we use 32-bit
address and size cells. This has the nice feature of us being able to
reuse the DT for 32-bit kernels as well.
This .dtsi lists the hardware that we support so far.

Changelog v1 .. v2:
- remove compatible string from the .dtsi
- amend compatible names to include sun50i
- drop PSCI 0.1 compatibility
- use lowercase hex digits in the GIC node too
- make pll6x2 an explicit fixed-factor clock
- make pll8 and pll8x2 proper clocks
- amend MMC clocks to match the manual, they are now mod0 clocks
- adapt MMC nodes to new MMC clocks
- add separate 4-pin and 2-pin definitions for the UARTs
- add I2C pins and driver nodes
- switch ahb_rst node to use normal compatible name, not the special,
  early-registration one.
Changelog v2 .. v3:
- remove leading zeros from node names' address part
- adapt PLL6/7/8 to proper PLL6 binding
- rename PLL6 to PLL7
