pcie_get_aspm_reg() mostly reads ASPM-related registers, but in some cases it also updates the value read from PCI_L1SS_CAP based on LTR properties. Move this update to the point where the value is used to make the code more readable. No functional change intended, although previously we could clear PCI_L1SS_CAP_ASPM_L1_2 for both ends of the link, and now we'll only do it for the downstream end of a link. This shouldn't matter because we always test that bit by ANDing l1ss_cap for the upstream and downstream ends.

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.
