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 e359b4411c28 ("serial: stm32: fix threaded interrupt handling"). Delete also usart2 and uart7 DMA property to keep current behavior. Signed-off-by: Erwan Le Ray <erwan.leray@foss.st.com> Signed-off-by: Alexandre Torgue <alexandre.torgue@foss.st.com>
