[PATCH v3] drm: Only select I2C_ALGOBIT for drivers that actually need it

[Uwe Kleine-König]

While working on a drm driver that doesn't need the i2c algobit stuff I
noticed that DRM selects this code even though 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.
