drm/drm_crtc: Introduce sharpness strength property
Introduce a new crtc property "SHARPNESS_STRENGTH" that allows
the user to set the intensity so as to get the sharpness effect.
The value of this property can be set from 0-255.
It is useful in scenario when the output is blurry and user
want to sharpen the pixels. User can increase/decrease the
sharpness level depending on the content displayed.
v2: Rename crtc property variable [Arun]
Add modeset detail in uapi doc[Uma]
v3: Fix build issue
v4: Modify the subject line[Ankit]
