Subject: [PATCH] dt-bindings: Fix I2C bus node names in examples

I2C bus node names are expected to be just "i2c", if there is just one
such node in given example.  Replace remaining bad examples with
scripted:

  git grep -l '\si2c[0-9] {' Documentation/devicetree/ | xargs sed -i -e 's/i2c[0-9] {/i2c {/'

Suggested-by: Rob Herring <robh@...nel.org>

Like Rob's commit 20a72af11f41 ("dt-bindings: Fix SPI and I2C bus node
names in examples"). I checked also for SPI.

Rebased on Rob's tree - can you pick it up directly? Applies also on
linux-next, so I do not expect conflicts.
