[PATCH v2 5/5] arm64: dts: imx8mp-venice-gw74xx: add WiFi/BT module support

[Tim Harvey <tharvey@xxxxxxxxxxxxx>]

The GW74xx supports an on-board Laird Connectivity Sterling LWB5+ module
which uses a Cypress CYW4373W chip to provide 1x1 802.11 a/b/g/n/ac +
Bluetooth 5.2.

Add the proper device-tree nodes for it.
