[PATCH] I2C: w83781d: remove non-i2c sensor chips

This patch removes the support for the W83697HF and W83627THF chips from
the w83781d driver. These chips have no I2C/SMBus interface and are
better supported by the Super-I/O-based w83627hf driver. Documentation
was updated to reflect the support drop.

+This driver implements support for the Winbond W83781D, W83782D, W83783S,
+W83627HF chips, and the Asus AS99127F chips. We will refer to them
+collectively as W8378* chips.
 
 There is quite some difference between these chips, but they are similar
 enough that it was sensible to put them together in one driver.

 Detection of these chips can sometimes be foiled because they can be in
 an internal state that allows no clean access. If you know the address
