ArrowLake-H contains 3 different uarchs, LionCove, Skymont and Crestmont. It is different with previous hybrid processors which only contains two kinds of uarchs. This patch adds PMU support for ArrowLake-H processor, adds ARL-H specific events which supports the 3 kinds of uarchs, such as td_retiring_arl_h, and extends some existed format attributes like offcore_rsp to make them be available to support ARL-H as well. Althrough these format attributes like offcore_rsp have been extended to support ARL-H, they can still support the regular hybrid platforms with 2 kinds of uarchs since the helper hybrid_format_is_visible() would filter PMU types and only show the format attribute for available PMUs.

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.
