ARM: dts: stm32: Pull UART4 RX high on AV96
There is no dedicated pull resistor on the AV96 UART4 (console UART) pin. In case there is no UART adapter installed on the AV96, the line is floating and can trigger reception of garbage characters, which in turn can abort U-Boot autoboot. Add default pull up to mitigate this problem.
