[Intel-gfx] [PATCH] drm/i915: Don't store the max cursor width/height in the crtc

[Damien Lespiau]

Those values are, global, only used in one function and already stored
in mode_config.cursor_{width,height}.

As a result, this initialization code has been moved from the
crtc_init() function to the global modeset_init() one.

I also renamed CURSOR_{WIDTH,HEIGHT} to MAX_CURSOR_{WIDTH,HEIGHT} to be
more accurate about what these value really are.
