[PATCH 3/6] dtc: dt-check-style: Process property names with a question mark

[Krzysztof Kozlowski]

Devicetree spec allows question mark '?' in property names and such code
is also accepted by DTC, thus catch such properties as a valid code,
even if discouraged.  Otherwise certain rules checking for property
names would ignore that line.
