[PATCH v1 1/1] arm64: dts: freescale: imx8mm-var-dart-sonata: Fix TPM reset polarity

[Stefano Radaelli]

From: Stefano Radaelli <stefano.r at variscite.com>

The reset input of the ST33KTPM on the Sonata carrier is active low,
but its reset-gpios property is declared GPIO_ACTIVE_HIGH. This
reverses the asserted and deasserted levels of the reset signal.

Use GPIO_ACTIVE_LOW to describe the reset polarity correctly. This
fixes the TPM not responding on I2C and the resulting absence of
/dev/tpm0.

Fixes: 770aba46ea0f ("arm64: dts: imx8mm-var-dart: Add support for Variscite Sonata board")
