Without the SGM_REG_SEL clock enabled the cpu freezes if trying to
access registers used by MT7981 clock drivers itself.
Mark SGM_REG_SEL as critical to make sure it is always enabled to
prevent freezes on boot even if the Ethernet driver which prepares
and enables the clock is not loaded or probed at a later point.

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.
