[PATCH v4 0/2] Samsung Exynos 7870 DECON driver support

[Kaustabh Chakraborty]

This patch series aims at adding support for Exynos7870's DECON in the
Exynos7 DECON driver. It introduces a driver data struct so that support
for DECON on other SoCs can be added to it in the future.

It also fixes a few bugs in the driver, such as functions receiving bad
pointers.

Tested on Samsung Galaxy J7 Prime (samsung-on7xelte), Samsung Galaxy A2
Core (samsung-a2corelte), and Samsung Galaxy J6 (samsung-j6lte).
