[PATCH 04/16] ARM: dts: stm32: keep uart4 behavior on icore-stm32mp1-ctouch2

DMA configuration is added to uart nodes in stm32mp15x device tree.
Delete uart4 DMA property in icore-stm32mp1-ctouch2 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").
