Add a new property in qualcom bluetooth dts to identify the product
information, so the driver can load the proper firmware.

Several Qualcomm projects will use the same Bluetooth chip, each
focusing on different features. For instance, consumer projects
prioritize the A2DP SRC feature, while IoT projects focus on the A2DP
SINK feature. Due to the patch size, it is not feasible to include all
features in a single firmware.

Therefore, the 'product-variant' devicetree property is used to provide
product information for the Bluetooth driver to load the appropriate
firmware.

The driver will parse 'product-variant' to load firmware from different
directories. If it's not defined in dts, the default firmware will be
loaded, which is compatible with the existing implementaion.
