hwmon: (adt7x10) Add alarm interrupt support
This allows an userspace application to poll() on the alarm files to get
notified in case of a temperature threshold event.

hwmon: (adt7410) Add support for the adt7310/adt7320
The adt7310/adt7320 is the SPI version of the adt7410/adt7420. The register map
layout is a bit different, i.e. the register addresses differ between the two
variants, but the bit layouts of the individual registers are identical. So both
chip variants can easily be supported by the same driver. The issue of non
matching register address layouts is solved by a simple look-up table which
translates the I2C addresses to the SPI addresses.
The patch moves the bulk of the adt7410 driver to a common module that will be
shared by the adt7410 and adt7310 drivers. This common module implements the
driver logic and uses a set of virtual functions to perform IO access. The
adt7410 and adt7310 driver modules provide proper implementations of these IO
accessor functions for I2C respective SPI.

hwmon: (adt7410) Don't re-read non-volatile registers
Currently each time the temperature register is read the driver also reads the
threshold and hysteresis registers. This increases the amount of I2C traffic and
time needed to read the temperature by a factor of ~5. Neither the threshold nor
the hysteresis change on their own, so once we have read them, we should be able
to just use the cached value of the registers. This patch modifies the code
accordingly and only reads the threshold and hysteresis registers once during
probe.

hwmon: Driver for ADT7410
This patch brings basic support for the Analog Devices ADT7410 temperature
sensor. The following functionality has been implemented:
* get current temperature
* get/set minimum, maximum and critical temperature
* get/set hysteresis
* get alarm events for minimum, maximum and critical temperature
All implemented sysfs attributes have been sucessfully tested at temperatures
of 15°C to 40°C.
