This patch adds the retry of btsoc initialization when it fails. There are reports that the btsoc initialization may fail on some platforms but the repro ratio is very low. The symptoms is the firmware downloading failed due to the UART write timed out. The failure may be caused by UART, platform HW or the btsoc itself but it's very difficlut to root cause, given the repro ratio is very low. Add a retry for the btsoc initialization can work around most of the failures and make Bluetooth finally works.

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.
