Introduce intel_scanlines_to_usecs() as a counterpart to intel_usecs_to_scanlines(). We'll have some use for this in DSB code as we want to do relative scanline waits to evade the delayed vblank, but unfortunately DSB can't do relative scanline waits (only absolute). So we'll instead convert the relative scanline count to usec and do a relative usec wait instead (which the DSB knows how to do).

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 reStructuredText 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.
