Adjust the parameters in mtk_drm_gamma_set_common()
  - add (struct device *dev) to get lut_diff from gamma's driver data
  - remove (bool lut_diff) and use false as default value in the function

Fixes: 051524cbe62d ("FROMGIT: drm/mediatek: Add lut diff flag for new gamma hardware support")

This function is called by both aal and gamma driver, so I would like
to pass struct device dev because priv data of aal and gamma are
different. Make this function command for both aal and gamma driver.

Hi CK, 

Thanks for the reviews.

I think handle the priv data of AAL in the gamma_set_common function
will make this function coupling with AAL.
So I'll drop this patch and move the gamma priv data to gamma_set and
just pass the necessary parameters for gamma_set_common.
