i2c: Let users select algorithm drivers manually again
In kernel 2.6.26, the ability to select I2C algorithm drivers manually was removed, as all in-kernel drivers do that automatically. However there were some complaints that it was a problem for out-of-tree I2C bus drivers. In order to address these complaints, let's allow manual selection of these drivers again, but still hide them by default for better general user experience. This closes bug #11140: http://bugzilla.kernel.org/show_bug.cgi?id=11140 Signed-off-by: Jean Delvare <khali@linux-fr.org>

+ Some I2C bus drivers require so-called "I2C algorithm" modules
