Bluetooth: Add support for Broadcom BCM20702A0 variants firmware download
This requires the flag BTUSB_BCM_PATCHRAM to work.

The firmware was extracted from a Windows 7 32-bit installation
and converted from 'hex' to 'hcd' for use in Linux.
The firmware is named "BCM20702A0_001.001.024.0156.0204.hex"
and is located in "%SYSTEMROOT%\system32\drivers\"
(md5 d126e6c4e0e669d76c38cf9377f76b7f)
(sha1 145d1850b2785a953233b409e7ff77786927c7d2)
The firmware file is also available as a download at
http://support.ts.fujitsu.com/Download/
contained in "FTS_WIDCOMMBluetoothSoftware_6309000_1072149.zip"
Search for the file Win32/bcbtums-win7x86-brcm.inf in the archive,
look for the vendor and product ID of your adapter, see the section
'devices' in that file to find out what device name it uses. See
the device entry in the inf file (in my case it was 'RAMUSBE031')
to find out which hex file you need to convert to hcd for upload
'hcd' file should be placed at "brcm/BCM20702A0-0489-e031.hcd"
inside the firmware directory (e.g. "/lib/firmware")
