[PATCH 3/3] drm/aperture: Inline fbdev conflict helpers into aperture helpers

[Thomas Zimmermann]

Fbdev's helpers for handling conflicting framebuffer drivers are
related to framebuffer apertures, not console emulation. Therefore
remove them from drm_fb_helper.h and inline them into the aperture
helpers. No functional changes.
