Recently non DT support from Exynos platform is removed and hence
removing non DT support from the driver also. This will help in easy
maintainence.

This code simplifies the zone handling to use the trip information passed
by the TMU driver and not the hardcoded macros. This also helps in adding
more zone support.

This patch removes the error return in the bind/unbind routine

TMU urgently sends active-high signal (thermal trip) to PMU, and thermal
tripping by hardware logic. Thermal tripping means that PMU cuts off the
whole power of SoC by controlling external voltage regulator.

This patch migrates the TMU register definition/bitfields to data file. This
is needed to support SoC's which use the same TMU controller but register
validity, offsets or bitfield may slightly vary across SOC's.

This patch adds entries min_efuse_value, max_efuse_value, default_temp_offset,
trigger_type, cal_type, trim_first_point, trim_second_point, max_trigger_level
trigger_enable in the TMU platform data structure. Also the driver is modified
to use the data passed by these new platform memebers instead of the constant
macros. All these changes helps in separating the SOC specific data part from
the TMU driver.

This patch adds some extra register bitfield definations and cleans
up the code to prepare for moving register macros and definations inside
the TMU data section. In this code cleanup the TMU enable bit is correctly used
as bit0 and bit1 is taken care which is reserve bit.

This patch renames and moves include/linux/platform_data/exynos_thermal.h to
drivers/thermal/samsung/exynos_tmu.h. This file movement is needed as exynos
SOC's are not supporting non-DT based platforms and this file now just contains
exynos tmu driver related definations.
Also struct freq_clip_table is now moved to exynos_thermal_common.c as it fixes
the compilation issue occuring because now this new tmu header file is included
in tmu driver c file and not in the common thermal header file.

This code bifurcates exynos thermal implementation into common and sensor
specific parts. The common thermal code interacts with core thermal layer and
core cpufreq cooling parts and is independent of SOC specific driver. This
change is needed to cleanly add support for new TMU sensors.
