While working on a drm driver that doesn't need the i2c algobit stuff I
noticed that DRM selects this code even tough only 8 drivers actually use
it. While also only some drivers use i2c, keep the select for I2C for the
next cleanup patch. Still prepare this already by also selecting I2C for
the individual drivers.
