Instead of open coding the polling of the lock status, use the handy readl_relaxed_poll_timeout for this. As the pll locking is normally blazingly fast and we don't want to incur additional delays, we're not doing any sleeps similar to for example the imx clk-pllv4 and define a very safe but still short timeout of 1ms.

README
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.
