QCA BTSOC NVM is a customized firmware file and different vendors may want to have different BTSOC configuration (e.g. Configure SCO over PCM or I2S, Setting Tx power, etc.) via this file. This patch will allow vendors to download different NVM firmware file by reading a device property "firmware-name".
