ARM: dts: stm32: keep uart4 behavior on stm32mp157c-lxa-mc1
DMA configuration is added to uart nodes in stm32mp15x device tree. Delete uart4 DMA property in stm32mp157c-lxa-mc1 board device tree to keep console in irq mode, as DMA support for console has been removed from the driver by commit e359b4411c28 ("serial: stm32: fix threaded interrupt handling").
