ASoC: tegra: Read and use the GPIO flags of the headphone detect
The headphone detect was hardcoded to low-active, use the flags from DT to allow high-active as well. Signed-off-by: Alban Bedel <alban.bedel@avionic-design.de> Acked-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Mark Brown <broonie@kernel.org>
