[igt-dev] [PATCH i-g-t 3/5] lib/kms: Drop igt_display_init

[Daniel Vetter <daniel.vetter@ffwll.ch>]

If you need the high-level functions, then you probably need a
full display. Unexport the non-requiring version, and adjust the
documentation. This also gives us proper docs for the recently
added igt_display_require.
