W83792D use pwm register low 4 bits to store PWM/DC value, bit 7
is used to store fan PWM/DC mode. The store_pwm function did not
convert the pwm input correctly, so it may change the fan mode
when new value is set.

This fix the problem. Change the "index" value of pwm*_mode
and pwm* SENSOR_ATTR to simplify code.

Now that i2c_add_driver() doesn't need the module owner to be set by
hand, we can delete it from the drivers.  This patch catches all of the
drivers that I found in the current tree (if a driver sets the .owner by
hand, it's not a problem, just not needed.)

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.

The only part left in i2c-sensor is the VRM/VRD/VID handling code.
This is in no way related to i2c, so it doesn't belong there. Move
the code to hwmon, where it belongs.

Note that not all hardware monitoring drivers do VRM/VRD/VID
operations, so less drivers depend on hwmon-vid than there were
depending on i2c-sensor.

The only thing left in i2c-sensor.h are module parameter definition
macros. It's only an extension of what i2c.h offers, and this extension
is not sensors-specific. As a matter of fact, a few non-sensors drivers
use them. So we better merge them in i2c.h, and get rid of i2c-sensor.h
altogether.

I would like to announce support for W83792D chip. This driver was developed

plus various code fixes and codingstyle cleanups. I would like to thank Winbond

Separate patch for documantation and hwmon class register will follow.
