[2/3] arm64: dts: allwinner: a64: Add WiFi/BT header on SoPine

Commit Message

Peter Robinson Sept. 1, 2024, 12:21 p.m. UTC

This adds all the pin mappings on the WiFi/BT header on
the SoPine baseboard/A64-LTS. They're disabled by default
as the modules don't ship by default. This includes, where
they haven't been already, UART1 for BT and mmc1 for WiFi.
