The gscaler has hardware rotation limits that need to be hardcoded
into driver. Distinguish them and add them to the property list.
The hardware rotation limits are related to the cropped source size.
When swap occurs, use rot_max size instead of crop_max size.
Also the scaling limits are related
Exynos 5250 and 5420 have different hardware rotation limits. However,
currently it uses only one compatible - "exynos5-gsc". Since we have

Hello all,
The gscaler has hardware rotation limits. So this patch set support
the rotate hardware limits of gsc.
To avoid problems with bisectability, patches 1~4 must be merged and
then merged 5 and 6.

- Fixed of_match_node() to of_device_get_match_data() in drm gsc driver.
