Draft: qcom: add firmware for the Xiaomi Poco F1 onboard WiFi on sdm845

Draft, because dependencies are:

• getting mainline patch merged, see [v1] https://lore.kernel.org/all/20251111-xiaomi-beryllium-firmware-v1-0-836b9c51ad86@ixit.cz/
• https://github.com/qca/qca-swiss-army-knife/pull/13 (support for the FW_FEATURES)

Xiaomi Poco F1 (beryllium) needs specific firmware quirk, so let's put it here.
