Pull the vblank delay computation into a separate function. We'll need more logic here soon and we don't want to pollute intel_crtc_compute_config() with low level details. We'll use HAS_DSB() to determine if any delay might be required or not because delayed vblank only really exists for the purposes of the DSB. It also doesn't event exists on any pre-tgl platforms, which also don't have DSB. I was midly tempted to check for the enable_dsb modparam here actually, but as that can be changed dynamically via debugfs we'd need to either reconfigure it on the fly or force a modeset. Neither will happen currently, so we'll just assume DSB may be used of the platform supports it.

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.
