Add DMA configuration to UART nodes in stm32mp15x (SOC level) and
remove it at board level to keep current PIO behavior when needed.
For stm32-ed1 and stm32-dkx boards, UART4 (console) and UART7
(no HW flow control pin available) are kept in PIO mode, while USART3
is now configured in DMA mode.
UART4 (console UART) has to be kept in irq mode, as DMA support for
console has been removed from the driver by commit e359b4411c28
("serial: stm32: fix threaded interrupt handling").
For other stm32mp15x-based boards, current configuration is kept for
all UART instances.
