drm/i915/display: start a buffer object abstraction layer The display code needs to deal with gem objects, and mostly uses struct drm_i915_gem_object. That's not great, because for xe we need to redefine it struct xe_bo during build. Start a common interface using struct drm_gem_object, with separate implementations for i915 and xe. For starters, convert i9xx_wm.c to use it.

drm/i915: Add intel_bo_panic_setup() and intel_bo_panic_finish() Implement both functions for i915 and xe, they prepare the work for drm_panic support. They both use kmap_try_from_panic(), and map one page at a time, to write the panic screen on the framebuffer.

drm/i915: Add intel_bo_alloc_framebuffer() Encapsulate the struct intel_framebuffer into an xe_framebuffer or i915_framebuffer, and allow to add specific fields for each variant for the panic use-case. This is particularly needed to have a struct xe_res_cursor available to support drm panic on discrete GPU.
