linux-firmware: Bring up wifi/ble interface on rpi3

Browse Source 
Currently the firmware is installed but kernel fails to load it
due this .txt file missing in the firmware directory and it ends
up with wifi/bluetooth i/f not being initialized. The error is
also in dmesg

[    3.120991] usbcore: registered new interface driver brcmfmac
[    3.148240] brcmfmac mmc1:0001:1: Direct firmware load for brcm/brcmfmac43430-sdio.txt failed with error -2

After applying this patch now ifconfig -a can list wlan0 interface
successfully.
