hwmon: (w83781d) Drop W83627HF support

The W83627HF hardware monitoring features are supported by the
w83627hf driver for several years now. Support by the w83781d has
been advertised as deprecated 6 months ago, it's about time to see
it go.

 Description
 -----------
 
-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.
+This driver implements support for the Winbond W83781D, W83782D, W83783S
+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.
-The W83627HF chip is assumed to be identical to the ISA W83782D.
 The Asus chips are similar to an I2C-only W83782D.
