[PATCH v1 13/14] arm64: dts: imx8mq-librem5: Reduce I2C frequency to 384kHz

[Martin Kepplinger]

From: Sebastian Krzyszkowiak <sebastian.krzyszkowiak@xxxxxxx>

According to imx8mq errata (ERR007805):

> To meet the clock low period requirement in fast speed mode,
> SCL must be configured to 384KHz or less.

Note that the imx i2c driver already implements this erratum and works
around it. This is only for the description to reflect reality.
