ARM: dts: stm32: keep uart4 behavior on stm32mp157c-ed1 

DMA configuration is added to uart nodes in stm32mp15x device tree.
Delete uart4 DMA property in stm32mp157c-ed1 board device tree to keep
console in irq mode, as DMA support for console has been removed from
the driver by commit e359b4411c ("serial: stm32: fix threaded
interrupt handling").
