This commit moves i8k driver to hwmon tree under name dell-smm-hwmon which is
better name then abbreviation i8k. For backward compatibility is added macro
MODULE_ALIAS("i8k") so modprobe will load driver also old name i8k. CONFIG_I8K
compile option was not changed.

This commit also adds me as maintainer of this new dell-smm-hwmon driver and
remove Guenter Roeck from list who is implicit maintainer all hwmon drivers.

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.
