[PATCH 2.4] i2c cleanups, second wave (4/5)

[Jean Delvare]

This patch doesn't really focus on the i2c subsystem, but one part of it
belongs to this subsystem. It fixes the dependancies between the various
SCx200 drivers, which happen to be incorrect at the time being. This is
a modified version of a patch I had previously submitted on the LKML,
but wasn't quite correct.

The patch also fixes Configure.help a bit for these drivers.

I've sent a similar (but smaller) patch to Greg KH for Linux 2.6, which
also has a few incorrectnesses in SCx200 driver dependancies.

Merry Christmas everyone :)
