[RFC PATCH V2 6/6] media: platform: mtk-mdp3: Add struct tuning_addr to identify user tuning data

[<frederic.chen@mediatek.com>]

From: Frederic Chen <frederic.chen@mediatek.com>

We added a struct tuning_addr which contains a field "present"
so that the driver can tell the firmware if we have user tuning
dataor not.
