drm/edid: add drm_edid_raw() to access the raw EDID data
Unfortunately, there are still plenty of interfaces around that require a struct edid pointer, and it's impossible to change them all at once. Add an accessor to the raw EDID data to help the transition. While there are no such cases now, be defensive against raw EDID extension count indicating bigger EDID than is actually allocated.
