docs: thermal: convert to ReST

Rename the thermal documentation files to ReST, add an
index for them and adjust in order to produce a nice html
output via the Sphinx build system.

At its new index.rst, let's add a :orphan: while this is not linked to
the main index.rst file, in order to avoid build warnings.

-Kernel driver exynos_tmu
-=================
-
-Supported chips:
-* ARM SAMSUNG EXYNOS4, EXYNOS5 series of SoC
-  Datasheet: Not publicly available
-
-Authors: Donggeun Kim <dg77.kim@samsung.com>
-Authors: Amit Daniel <amit.daniel@samsung.com>

-TMU controller Description:
----------------------------
-
-This driver allows to read temperature inside SAMSUNG EXYNOS4/5 series of SoC.
-
-The chip only exposes the measured 8-bit temperature code value
-through a register.
-Temperature can be taken from the temperature code.
-There are three equations converting from temperature to temperature code.
-
-The three equations are:
-  1. Two point trimming
-	Tc = (T - 25) * (TI2 - TI1) / (85 - 25) + TI1
-
-  2. One point trimming
-	Tc = T + TI1 - 25
-
-  3. No trimming
-	Tc = T + 50
-
-  Tc: Temperature code, T: Temperature,
-  TI1: Trimming info for 25 degree Celsius (stored at TRIMINFO register)
-       Temperature code measured at 25 degree Celsius which is unchanged
-  TI2: Trimming info for 85 degree Celsius (stored at TRIMINFO register)
-       Temperature code measured at 85 degree Celsius which is unchanged
-
-TMU(Thermal Management Unit) in EXYNOS4/5 generates interrupt
-when temperature exceeds pre-defined levels.
-The maximum number of configurable threshold is five.
-The threshold levels are defined as follows:
-  Level_0: current temperature > trigger_level_0 + threshold
-  Level_1: current temperature > trigger_level_1 + threshold
-  Level_2: current temperature > trigger_level_2 + threshold
-  Level_3: current temperature > trigger_level_3 + threshold
-
-  The threshold and each trigger_level are set
-  through the corresponding registers.
-
-When an interrupt occurs, this driver notify kernel thermal framework
-with the function exynos_report_trigger.
-Although an interrupt condition for level_0 can be set,
-it can be used to synchronize the cooling action.
-
-TMU driver description:
------------------------
-
-The exynos thermal driver is structured as,
-
-					Kernel Core thermal framework
-				(thermal_core.c, step_wise.c, cpu_cooling.c)
-								^
-								|
-								|
-TMU configuration data -------> TMU Driver  <------> Exynos Core thermal wrapper
-(exynos_tmu_data.c)	      (exynos_tmu.c)	   (exynos_thermal_common.c)
-(exynos_tmu_data.h)	      (exynos_tmu.h)	   (exynos_thermal_common.h)
-
-a) TMU configuration data: This consist of TMU register offsets/bitfields
-		described through structure exynos_tmu_registers. Also several
-		other platform data (struct exynos_tmu_platform_data) members
-		are used to configure the TMU.
-b) TMU driver: This component initialises the TMU controller and sets different
-		thresholds. It invokes core thermal implementation with the call
-		exynos_report_trigger.
-c) Exynos Core thermal wrapper: This provides 3 wrapper function to use the
-		Kernel core thermal framework. They are exynos_unregister_thermal,
-		exynos_register_thermal and exynos_report_trigger.
