ARM: dts: stm32: keep uart nodes behavior on stm32mp157a-stinger96 



DMA configuration is added to uart nodes in stm32mp15x device tree.
Delete uart4 DMA property in stm32mp157a-stinger96 board device tree to
keep console in irq mode, as DMA support for console has been removed
from the driver by commit e359b441 ("serial: stm32: fix threaded
interrupt handling").
Delete also usart2 and uart7 DMA property to keep current behavior.
