It's to be able to have a config file to generate kernels supporting
preliminary hardware, without having to always add the command line
parameter or carry a patch or changing the bootloader configuration.

That's the default, you don't have to make it explicit (but of course it
doesn't hurt). make oldconfig with this new option gives:

  Enable preliminary support for prerelease Intel hardware by default
  (DRM_I915_PRELIMINARY_HW_SUPPORT) [N/y/?] (NEW)

The Kconfig files have both styles, 2 spaces or 1 space after the '.'.
