media: platform: mtk-mdp3: add MediaTek MDP3 driver
This patch adds driver for MediaTek's Media Data Path ver.3 (MDP3).
It provides the following functions:
color transform, format conversion, resize, crop, rotate, flip
and additional image quality enhancement.
The MDP3 driver is mainly used for Google Chromebook products to
import the new architecture to set the HW settings as shown below:
User -> V4L2 framework
-> MDP3 driver -> SCP (setting calculations)
-> MDP3 driver -> CMDQ (GCE driver) -> HW
Each modules' related operation control is sited in mtk-mdp3-comp.c
Each modules' register table is defined in file with "mdp_reg_" prefix
GCE related API, operation control sited in mtk-mdp3-cmdq.c
V4L2 m2m device functions are implemented in mtk-mdp3-m2m.c
Probe, power, suspend/resume, system level functions are defined in
mtk-mdp3-core.c
[hverkuil: add 'depends on REMOTEPROC']
