ASoC: codecs: wsa883x: Use proper shutdown GPIO polarity

[ Upstream commit ec5dba73f7ba10797904cf18092d2e6975a22147 ]

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.
