In preparation of adding support for loading the initrd via a special device path, add the struct definition of a vendor GUIDed device path node to efi.h. Since we will be producing these data structures rather than just consumsing the ones instantiated by the firmware, refactor the various device path node definitions so we can take the size of each node using sizeof() rather than having to resort to opaque arithmetic in the static initializers. While at it, drop the #if IS_ENABLED() check for the declaration of efi_get_device_by_path(), which is unnecessary, and constify its first argument as well.

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.
