ipa: rkisp1: Add support of Filter control

Denoise and Sharpness filters will be applied by RkISP1 during the
demosaicing step. The denoise filter is responsible for removing noise
from the image, while the sharpness filter will enhance its acutance.

Add filter algorithm with denoise and sharpness values based on user
controls.
