Add rk3318 A95X Z2 board.

What works:
 adc key
 emmc
 ethernet
 hdmi
 gpu
 ir
 mmc
 sd card
 vop
 usb2
 uart2

Not tested:
 av
 uart0 / bt
 spdif
 wifi

No support in mainline:
 usb3 (works with manufacturer driver)
 front display (works with custom gpio driver AD1628/HT1628)

Problems:
 U-boot only starts on emmc, then loads kernel from sd card or emmc.

 Hdmi hotplug detects DVI modes, but marks them all BAD.
 The dw-hdmi driver needs more pre_pll_cfg_table entries.
 Slow boot behavior. Screen available way after boot. (no penguins)

 GPU support for Debian is not up to date. (old version)
 Use Github version instead.
 Test with glmark2-es2-drm gives glmark2 Score: 29
 Kernel log:
  lima ff300000.gpu: pp pp0 reset time out
  lima ff300000.gpu: pp pp1 reset time out
 No mainline support for GPU thermal and voltage to frequency.
 PWM1 supply connected to DMC, GPU and vcodec.

 The box only has a model name. Vendor prefix not verified.

 Etc.

Changed V2:
  add vendor prefix
  changed compatible string
  restyle
  removed usb3 regulator node
  changed led active high to active low
