DMA configuration is added to uart nodes in stm32mp15x device tree.
Delete uart4 DMA property in stm32mp1-microdev2.0 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").
Delete also uart8 DMA property to keep current behavior.
