[PATCH] ASoC: codecs: wsa883x: Use proper shutdown GPIO values
The shutdown GPIO is active_low (sd_n), but this depends on actual board layout. Linux drivers should only care about logical state, where high (1) means shutdown and low (0) means do not shutdown.
Invert the GPIO to match logical value.

I will also update the example in bindings. Not a blocker for this patch, but better to keep these together, so there will be a v2.
Best regards, Krzysztof
