[PATCH 18/18] thermal: exynos: remove trip reporting to user-space

[Bartlomiej Zolnierkiewicz <b.zolnierkie@samsung.com>]

Remove trip reporting to user-space - I'm not aware of any user-space
program which relies on it and there is a thermal user-space governor
which does it in proper way nowadays.
