ARM: dts: stm32mp1: add pull-up on serial rx of console connected to STLINK

Avoid U-Boot auto-boot interruption for line break detection
on console when the RX line connected to STLINK is floating
(-IO error in getc cause by framing error and testc return 1)
Same workaround is applied on all the STMicroelectonics board.
