Adding PineH64 SBC support

[dmanla]

I have added the "microcontroller" file and "board" file for the Allwinner H6 based PineH64. I believe these are the only necessary files for Blinka compatibility.

I followed the guide provided by Adafruit at the following link:
https://learn.adafruit.com/adding-a-single-board-computer-to-blinka/

I will also be creating a pull request for adafruit_platformdetect to add PineH64 detection.

Good afternoon,

I noticed my pull request has failed the check due to a formatting issue. I am unsure what this issue is. When creating the file I used the pine64.py file as a reference. I see no discrepancies in their formatting.

Thanks. You will probably also need to add an elif line to board.py and the checks will fail until your PlatformDetect PR is in.

Could you please add the board to this huge else-if block:

PineH64 has now been added to the large elsif block.

Looks like you're missing an asterisk at the end of your import statement.

This line should be:
from adafruit_blinka.board.pineH64 import *

[dmanla]

Hey,

Sorry for the super long wait. I added the asterisk.

Thanks for following up. We need to get adafruit/Adafruit_Python_PlatformDetect#90 merged in before this will pass and there's some long comment lines stopping it from passing the checks.

This looks good.
