This adds support to download helper FW file for the legacy NXP chipset 88w8997 for the btnxpuart driver. This helper FW file is necessary to set the bootloader baudrate to 3000000 after which the actual BT FW file can be downloaded. This change helps bring the FW download time from around 10 sec to less than 2 sec for 88w8997 chip. For newer chipsets, both V1 and V3 bootloader, driver sends the cmd5 and cmd7 to the chip bootloader, and does not need a helper FW file.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
