[PATCH v2 1/3] docs: i2c: i2c-topology: fix incorrect heading

[luca . ceresoli]

From: Luca Ceresoli <luca.ceresoli@xxxxxxxxxxx>

"Etc" here was never meant to be a heading, it became one while converting
to ReST.

It would be easy to just convert it to plain text, but rather remove it and
add an introductory text before the list that conveys the same meaning but
with a better reading flow.

Fixes: ccf988b66d69 ("docs: i2c: convert to ReST and add to driver-api bookset")
Signed-off-by: Luca Ceresoli <luca.ceresoli@xxxxxxxxxxx>

 There are a couple of reasons for building more complex I2C topologies
 than a straight-forward I2C bus with one adapter and one or more devices.
 
+Some example use cases are:

 1. A mux may be needed on the bus to prevent address collisions.

 These constructs are represented as I2C adapter trees by Linux, where
 each adapter has a parent adapter (except the root adapter) and zero or
 more child adapters. The root adapter is the actual adapter that issues
