Add basic Rockchip rk3128 DT support.

Features:
  Quad-core ARM Cortex-A7MP Core processor
  Clock & reset unit
  Power management unit
  Interrupt controller
  DMAC
  6x 64 bits Timers
  4x PWMs
  1x 32 bits watchdog

Internal memory:
  Internal BootRom
  Internal SRAM 8KB

External memory:
  Dynamic Memory Interface (DDR3/DDR3L/LPDDR2)
  Nand Flash Interface
  eMMC Interface
  SD/MMC Interface

Connectivity:
  SDIO interface
  SPI Controller
  3x UART controller
  4x I2C controllers
  4x groups of GPIO (GPIO0~GPIO3), 32 GPIOs per group
  USB Host2.0
  USB OTG2.0

The Linux kernel has added a rk3128 clock driver in the past,
but the DT is still missing.

In U-boot the rk3128 DT doesn't conform the latest bindings
and also the pin definition don't match the TRM.

On request from the U-boot maintainers I submit a basic rk3128 DT.

Based on:
https://source.denx.de/u-boot/u-boot/-/blob/master/arch/arm/dts/rk3128.dtsi
https://github.com/rockchip-linux/kernel/blob/develop-4.4/arch/arm/boot/dts/rk312x.dtsi

rk3128 datasheet:

NOT TESTED WITH HARDWARE
NO THERMAL PROTECTION

===

Request:
  Help with testing on hardware.

Changed V2:
  rk3128.dtsi:
    remove aliases
    add gic interrupts mask defines
    add virtual timer interrupts

  rk3128-evb.dts:
    use generic node names
    remove underscores in node names
    add more aliases
    sort
