Input: gpio-keys-polled - don't use unit-address with button nodes
The change corrects an example in device tree documentation section,
because button/key device nodes don't contain reg property there is
no need to declare unit-address, and address and size cell properties
are also redundant.
At the moment a compilation of the hypothetical original example
should produce W=1 level warnings, and it is better to stop spreading
misusage of the polled gpio keys device tree binding through this
example.
