[ Upstream commit b7df21c59739cceb7b866c6c5e8a6ba03875ab71 ]

The WCD9370 audio codec reset line on QCM6490 IDP should be active-low, but
the device tree described it as active-high. As a result, the codec is
kept in reset and fails to reset the SoundWire, leading to timeouts
and ASoC card probe failure (-ETIMEDOUT).

Fix the reset GPIO polarity to GPIO_ACTIVE_LOW so the codec can properly
initialize.
