'pcie_link_status' is a global variable which is being used as a mask to know which virtual bridges are or not enabled. Instead of this extract a new 'mt7621_pcie_init_virtual_bridges' function where a similar local variable is used for the same task. This allow us to properly configure the virtual PCI-PCI bridges in configuration registers of the mt7621 pci controller. For a correct initiation of which is connected use 'enabled' field of 'mt7621_pcie_port' struct. With this change driver probe function gets a bit cleaner and readable.

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.
