mec1322: handle dummy GPIO gracefullystabilize-springlte-5116.46.Bstabilize-5116.88.Bstabilize-5116.53.Bstabilize-5116.115.Bstabilize-5116.113.Brelease-R33-5116.B
When a GPIO signal is defined by GPIO_SIGNAL_NOT_IMPLEMENTED, it should
still be able to call various GPIO methods on that GPIO signal. Since
__builtin_clz dies when the value passed in is zero, we need to check
this before calling __builtin_clz.
