data: add PinePhone Pro config

The PinePhone Pro uses the same EG25 modem as the OG PinePhone, but with
a different SoC. It also uses an ALC5616 audio codec directly hooked up
to the modem (which is I2S master in this case).

The config is therefore almost identical to the PinePhone rev1.2 except
for the gpios, UART port used and `AT+QDAI` config (to account for the
different audio setup).
