arm64: dts: imx8mm-kontron: Disable pullups for I2C signals on OSM-S i.MX8MM

Browse Source 
[ Upstream commit 96293af54f6aa859015d8ca40a1437d3115ad50c ]

There are external pullup resistors on the board and due to silicon
errata ERR050080 let's disable the internal ones to prevent any
unwanted behavior in case they wear out.
