Subject: [PATCH] arm64: dts: qcom: sm8150-hdk: enable WiFI support

Enable modem DSP and WiFI devices on the SM8150 HDK device. The HDK is
manufactured by Lantronix, but it attributed to Qualcomm, so the
calibration string uses Qualcomm as manufacturer.

For reference:

Note the device also uses updated wlanmdsp, so it will be updated with
firmware-name for WiFi once [1] is merged.
