[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.
