If the selected CPU hisi_pmu::on_cpu goes offline, driver will select a new online CPU from hisi_pmu::associated_cpus, or if no online CPU found the PMU context won't be migrated. However for uncore PMUs the associated CPUs are just a peference and it also works to schedule the events on any online CPUs. So add a fallback to choose an online CPU if no associated CPUs found.

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.
