ap6212a.inc: add support for AMPAK 6212A

Browse Source 
Add support for AMPAK 6212A module:
1) install kernel module
2) install firmware
3) create the required symlink with the AP6212 NVRAM file
Enable the support in the boards with the module, according to:
https://linux-sunxi.org/Table_of_Allwinner_based_boards
The link creation with compatible name works on kernels >= 5.0.
