This patch adds support for h/w mode calibration in the TMU controller.
Soc's like 5440 support this features. The h/w bits needed for calibration
setting are same as that of enum calibration_type.

This patch adds configuration data for exynos5440 soc. Also register
definations for the controller are added.

This patch modifies TMU controller to add changes needed to work with
exynos5440 platform. This sensor registers 3 instance of the tmu controller
with the thermal zone and hence reports 3 temperature output. This controller
supports upto five trip points. For critical threshold the driver uses the
core driver thermal framework for shutdown.

This patch adds support to handle multiple instances of the TMU controllers.
This is done by removing the static structure to register with the core thermal
and creating it dynamically for each instance of the TMU controller. The
interrupt is made shared type to handle shared interrupts. Now since the ISR needs
the core thermal framework to be registered so request_irq is moved after the core
registration is done.
Also the identifier of the TMU controller is extracted from device tree alias. This
will be used for TMU specific initialisation.

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 code splits the exynos tmu driver code into SOC specific data parts.
This will simplify adding new SOC specific data to the same TMU controller.
