thermal: exynos: always check for critical trip points existence
* Check for critical trip point existence in exynos_tmu_initialize()
so it is checked on all SoCs (except Exynos5433 for now).
* Use dev_err() instead of pr_err().
* Fix dev_err() to reference "device tree" not "of-thermal.c".
* Remove no longer needed check from exynos4412_tmu_initialize().
