arm64: dts: rockchip: add version-independent WiFi/BT nodes on Sige5

Browse Source 
ArmSoM Sige5 uses a soldered-on WiFi/BT module with WiFi on SDIO and BT
on UART. However, board v1.1 uses a Realtek based BL-M8852BS2, while
v1.2 uses a Broadcom based BW3752-50B1. They use the same pins and
controllers, but require different DT properties to enable.

Thankfully, the WiFi part at least works without explicitly listing it in
the device tree, albeit without OOB interrupt functionality.

Add required device tree nodes that do not depend on the board version so
that at least the WiFi module can appear on the SDIO bus.

WiFi OOB interrupt and Bluetooth function support are not enabled here, as
they require module specific properties.
