[PATCH 2.4] i2c cleanups, third wave (2/8)

[Jean Delvare <khali@linux-fr.org>]

Remove old debugging stuff ("SLO_IO") from two algorithms
(i2c-algo-bit and i2c-algo-ite). This is unused and wouldn't even
compile if commented out.

A similar patch was sent to Greg KH for linux 2.6 and was applied in
2.6.1-rc1.

Note that this patch was voluntarily generated using diff -U2, because
it contains only removals, so much context isn't required.
