[PATCH V4 7/8] drm/mediatek: using new factor for tvdpll in MT2701

[wangyan wang <wangyan.wang-NuS5LvNUpcJWk0Htik3J/w@public.gmane.org>]

From: chunhui dai <chunhui.dai-NuS5LvNUpcJWk0Htik3J/w@public.gmane.org>

The factor depends on the divider of DPI in MT2701, therefore,
we should fix this factor to the right and new one.
