arm64: dts: imx8mm-kontron: Disable pullups for I2C signals on SL/BL i.MX8MM
[ Upstream commit f19e5bb91d53264d7dac5d845a4825afadf72440 ]
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.
