drm/exynos: add gsc ipp driver
This patch adds IPP subsystem-based gsc driver for exynos5 series.
GSC is stand for General SCaler and supports the following features:
- image scaler/rotator/crop/flip/csc and input/output DMA operations.
- image rotation and image effect functions.
- writeback and display output operations.
- M2M operation to crop, scale, rotation and csc.
The below is GSC hardware path:
Memory------->GSC------>Memory
FIMD--------->GSC------>HDMI
FIMD--------->GSC------>Memory
Memory------->GSC------>FIMD, Mixer
This driver is registered to IPP subsystem framework to be used by user side
and user can control the GSC hardware through some interfaces of IPP subsystem
framework.
Changelog v1 ~ v5:
- added comments, code fixups and cleanups.
