The TCU clock gate on X1000 wasn't requested by the driver and could be gated automatically later on in boot, which prevents timers from running and breaks PWM. Add a workaround to support old device trees that don't specify the "tcu" clock gate. In this case the kernel will print a warning and attempt to continue without the clock, which is wrong, but it could work if "clk_ignore_unused" is in the kernel arguments.

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.
