Drop the open-coded register polling routines. Use readl_poll_timeout_atomic() in atomic state. Also adjust the delay time to 10us which seems more reasonable. Tested on NXP i.MX8MP and ROCKCHIP RK3588 boards, the break condition was met right after the first polling, no delay involved at all. So the 10us delay should be long enough for most cases.

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 reStructuredText 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.
