community/linux-edge: add initial support for pinebook pro
This commit enables a minimal set of config options to support (most of) the hardware in the pinebook pro. There are known missing config options to add support for certain features at this time but I haven't been able to figure out which ones are needed yet (they are working on my local configuration[0] though). The following are known issues:
- missing temperature sensor support
- PCIe errors in dmesg

Tested using the default u-boot package in alpine-edge with EFI boot.
