Most LM75-compatible chips can either sample much faster or with a
much better resolution than the original LM75 chip. So far the lm75
driver did not let the user take benefit of these improvements. Do it
now.

I decided to almost always configure the chip to use the best
resolution possible, which also means the longest sample time. The
only chips for which I didn't are the DS75, DS1775 and STDS75, because
they are really too slow in 12-bit mode (1.2 to 1.5 second worst case)
so I went for 11-bit mode as a more reasonable tradeoff. This choice is
dictated by the fact that the hwmon subsystem is meant for system
monitoring, it has never been supposed to be ultra-fast, and as a
matter of fact we do cache the sampled values in almost all drivers.

If anyone isn't pleased with these default settings, they can always
introduce a platform data structure or DT support for the lm75. That
being said, it seems nobody ever complained that the driver wouldn't
refresh the value faster than every 1.5 second, and the change made
it faster for all chips even in 12-bit mode, so I don't expect any
complaint.

Each of ST-Ericsson X500 chip set series consists of both ABX500 and DBX500
chips. This is ABX500 hwmon driver, where the abx500.c is a common layer for
all ABX500s, and the ab8500.c is specific for AB8500 chip. Under this designed
structure, other chip specific files can be added simply using the same common
layer abx500.c.

Some sysfs attributes are only supported on LTC2978 and not on LTC3880.
Update documentation to reflect which attributes are supported for which chips.

Output current attributes supported on LTC3880 were described as providing
input current values. Fix text to reflect that the attributes provide output
current values.

"reset history" attribute descriptions were misleading and seemed to imply
that all history was reset when writing a single attribute. Replace with more
accurate text.

Replace 'internal temperature" with "chip temperature". Temperature limits
not only apply to the chip temperature, but also to external temperatures
on LTC3880, so remove the word "chip" from the attribute description.

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.
