Use DEVICE_ATTR_RO for read only attributes and DEVICE_ATTR_RW for
read/write attributes. This simplifies the source code, improves
readbility, and reduces the chance of inconsistencies.
The conversion was done automatically using coccinelle. It was validated
by compiling both the old and the new source code and comparing its text,
data, and bss size.

The module test script for the adm1021 driver exposes a cache problem
when writing temperature limits. temp_min and temp_max are expected
to be stored in milli-degrees C but are stored in degrees C.

On a system with both MAX1617 and JC42 sensors, JC42 sensors can be misdetected
as LM84. Strengthen detection sufficiently enough to avoid this misdetection.
Also improve detection for ADM1021.
Modeled after chip detection code in sensors-detect command.

fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy

It's time to remove the int/unsigned int option. For this version
it'll simply give a warning, but it'll break next kernel version.

The ADM1023 temperature sensor supports higher resolution for its external

resolution available through the appropriate temperature sysfs nodes.
Curiously, this functionality was available in the 2.4 kernel driver (but
formatted in a less helpful manner).

Just about every i2c chip driver sets the I2C_DF_NOTIFY flag, so we
can simply make it the default and drop the flag. If any driver really
doesn't want to be notified when i2c adapters are added, that driver
can simply omit to set .attach_adapter. This approach is also more
robust as it prevents accidental NULL pointer dereferences.
