This adds the Samsung 1404-001221 NTC thermistor to the
NTC thermistor driver. As far as I can tell it is electrically
compatible with the Murata 47K NTC thermistor.
This thermistor is mounted in a variety of Samsung products.

This switches to retrieveing the configuration of the NTC
from generic firmware properties so that we get neutral from
device tree: now ACPI or, more importantly, software nodes
can be used to spawn NTC devices provided they have the
required properties.
This was inspired by the similar changes made to the IIO
drivers.
This was tested on the Ux500 HREF with the NTC devices
probing from device tree just as fine after this as before.

Before trying the custom method of reading the sensor
as raw and then converting, we want to use
iio_read_channel_processed_scale() which first tries to
see if the ADC can provide a processed value directly,
else reads raw and applies scaling inside of IIO
using the scale attributes of the ADC. We need to
multiply the scaled value with 1000 to get to
microvolts from millivolts which is what processed
IIO channels returns.
Keep the code that assumes 12bit ADC around as a
fallback.
This gives correct readings on the AB8500 thermistor
inputs used in the Ux500 HREFP520 platform for reading
battery and board temperature.

The thermal code uses int, long and unsigned long for temperatures
in different places.
Using an unsigned type limits the thermal framework to positive
temperatures without need. Also several drivers currently will report
temperatures near UINT_MAX for temperatures below 0°C. This will probably
immediately shut the machine down due to overtemperature if started below
0°C.
'long' is 64bit on several architectures. This is not needed since INT_MAX °mC
is above the melting point of all known materials.
Consistently use a plain 'int' for temperatures throughout the thermal code and
the drivers. This only changes the places in the drivers where the temperature
is passed around as pointer, when drivers internally use another type this is
not changed.

The function get_ohm_of_thermistor has both the measured voltage and the
pullup voltage available in microvolts. But it was promptly converting
both to millivolts before using them to calculate the thermistor
resistance. That conversion unnecessarily hurt the precision of the
calculation.
For example, take the ncpXXwb473 connected to 5000 mV and pulled down
through a 47000 ohm resistor. At 25 C, the resistance of the thermistor
is 47000 ohms. The measured voltage will be 2500 mV. If we measure
instead 2501 mV, then the calculated resistance will be 46962 ohms --
a difference of 38 ohms. So the precision of the resistance estimate
could be increased by 38X by doing the calculations in microvolts.

Different drivers request API extensions in of-thermal. For this reason,
additional callbacks are required to fit the new drivers needs.
The current API implementation expects the registering sensor driver
to provide a get_temp and get_trend callbacks as function parameters.
As the amount of callbacks is growing, this patch changes the existing
implementation to use a .ops field to hold all the of thermal callbacks
to sensor drivers.
This patch also changes the existing of-thermal users to fit the new
API design. No functional change is introduced in this patch.

In commit 9e8269de, support was added for ntc_thermistor devices being
declared in the device tree and implemented on top of IIO. With that
change, a dependency was added to the ntc_thermistor driver:
depends on (!OF && !IIO) || (OF && IIO)
This construct has the drawback that the driver can no longer be
selected when OF is set and IIO isn't, nor when IIO is set and OF is
not. This is a regression for the original users of the driver.
As the new code depends on IIO and is useless without OF, include it
only if both are enabled, and set the dependencies accordingly. This
is clearer, more simple and more correct.

CONFIG_HOTPLUG is going away as an option so __devexit_p is no longer
needed.

Fix Coverity warning: Calling strncpy with a maximum size argument of 20 bytes
on destination array "data->name" of size 20 bytes might leave the destination
string unterminated.
Fix by replacing strncpy() with strlcpy() and by using sizeof() to determine
the maximum string length.
