arm64: dts: imx8mm-kontron: Disable pull resistors for SD card signals on BL OSM-S board
[ Upstream commit 5a940ba3e4d7c8710c9073ff5d0ca4644d4da9db ]
Some signals have external pullup resistors on the board and don't need
the internal ones to be enabled. Due to silicon errata ERR050080 let's
disable the internal pull resistors whererever possible and prevent
any unwanted behavior in case they wear out.
