On physical machine we can save power by disabling clock of hot removed cpu. However as different platforms require different methods to configure clocks, the code is platform-specific, and probably belongs to firmware/pmu or cpu regulator, rather than generic arch/loongarch code. Also, there is no such register on QEMU virt machine since the clock/frequency regulation is not emulated. This patch removes the hard-coded clock register accesses in generic LoongArch cpu hotplug flow.

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.
