[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.
