arm64: dts: rockchip: Add AP6275P wireless support for Khadas Edge 2L

Browse Source 
The Khadas Edge 2L uses an Ampak AP6275P (BCM43752) PCIe
Wi-Fi 6 module.

Enable combphy0 and pcie0, add the Wi-Fi regulator and reset
pinctrl, and describe the PCIe Wi-Fi function so it can consume
the 32.768kHz LPO clock provided by the HYM8563 RTC.
