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.

Changes since v1
(20210514100142.1182997-1-u.kleine-koenig@pengutronix.de) from
2021-05-14:

 - rebased to next-20220909
   was something around v5.13-rc2 before, required to fix context
   changes in the nouveau Kconfig file. git am -3 handled it just fine.

I reverified that no new drivers were added that need a corresponding
select.

Best regards
Uwe
