drm/i915/fbdev: Implement fb_dirty for intel custom fb helper
After disconnecting damage worker from update logic it's left to fbdev
emulation implementation to have fb_dirty function. Currently intel
fbdev doesn't have it. This is causing problems to features (PSR, FBC,
DRRS) relying on dirty callback.
Implement simple fb_dirty callback to deliver notifications about updates
in fb console.
v4: Add proper Fixes tag and modify commit message
v3: Check damage clip
v2: Improved commit message and added Fixes tag
Fixes: f231af498c29 ("drm/fb-helper: Disconnect damage worker from update logic")
