Large ppGTT are differentiated by the requirement to go to four levels to address more than 32b. Given the introduction of more 4 level ppGTT with different sizes of addressable bits, rename i915_vm_is_48b() to better reflect the commonality of using 4 levels. Based on a patch by Bob Paauwe.

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.
