WIP: ARM: dts: qcom: Add basic DT for mdm9607 + Waveshare 4G HAT

Mostly an adjusted version of my device tree for MSM8909. Working functionality on the Waveshare 4G HAT: - UART - Boots into postmarketOS installed on SD card - USB - NAND (with some quirks) - Modem (mobile data works with ModemManager) Signed-off-by: Stephan Gerhold <[email protected]>
