The global screen_info state is only meant for architecture and firmware code. Replace its use in hyperv graphics drivers with the correct aperture helpers. Patches 1 and 2 update hyperv-drm and hyperv-fb to use the correct aperture helpers instead of screen_info for removing existing firmware framebuffers. Hyperv-fb also modifies screen_info for better use with kexec. While that update makes sense, it's not supposed to be done by the driver. Patch 3 adds similar code to sysfb and patch 4 removes the code from the driver. An intented side effect of this patchset is that all systems now benefit from better kexec support. After rebooting with kexec, the kernel operated on stale settings on screen_info. Patch 3 fixes this and the kexec kernel will use screen_info in any meaningful way.
