[PATCH 6/6] dtc: dt-check-style: Check for indentation also in continued lines of bindings example

[Krzysztof Kozlowski <krzysztof.kozlowski@oss.qualcomm.com>]

Add missing code in check_tab_in_yaml_example() for example in the
bindings to apply the same rule of discouraged tab character also for
continued lines (iterating over all DtsLines is not enough).
