ARM: dts: imx7d-pico: Describe the Wifi clock
[ Upstream commit c3b9ab5db11d8098ca7674175f12ab21cdce1bbb ] The Wifi chip should be clocked by a 32kHz clock coming from i.MX7D CLKO2 output pin, so describe the pinmux and clock hierarchy in the device tree to allow the Wifi chip to be properly clocked. Managed to successfully test Wifi with such change. Used the standard nvram.txt file provided by TechNexion, which selects an external 32kHz clock for the Wifi chip by default.
