The SC8280XP platform has seven PCIe controllers: two used with USB4, two 4-lane, two 2-lane and one 1-lane. Add a new "qcom,pcie-sc8280xp" compatible string and reuse the 1.9.0 ops. Note that the SC8280XP controllers need two or three interconnect clocks to be enabled. Model these as optional clocks to avoid encoding devicetree data in the PCIe driver. Note that the same could be done for the SM8450 interconnect clocks and possibly also for the TBU clocks.

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.
