thermal: exynos: always check for trips points existence
* Check for trip points existence in exynos_tmu_initialize() so it is
checked on all SoCs.
* Use dev_err() instead of pr_err().
* Fix dev_err() to reference "device tree" not "of-thermal.c".
* Remove no longer needed checks from exynos4210_tmu_initialize() and
get_th_reg().
