Replace the open-coded implementation for reading the PCIe DSN with pci_get_dsn(). The pci_get_dsn() function will perform two pci_read_config_dword calls to read the lower and upper config dwords. It bitwise ORs them into a u64 value. Instead of using put_unaligned_le32 to convert the value to LE32 format, just use the %016llX printf specifier. This will print the u64 correct, putting the most significant byte of the value first. Since pci_get_dsn() correctly orders the two dwords into a u64, this should produce equivalent results in less code.

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.
