[PATCH] I2C: drivers/i2c/chips/adm1026.c: use dynamic sysfs callbacks

Finally (phew!) this patch demonstrates how to adapt the adm1026 to
take advantage of the new callbacks, and the i2c-sysfs.h defined
structure/macros. Most of the other sensor/hwmon drivers could be
updated in the same way. The odd few exceptions (bmcsensors for
example) however might be better off with their own custom attribute
structure.
