ARM: dts: stm32: Configure qspi's mdma transfer to block for stm32mp151
Configure qspi's mdma from buffer transfer (max 128 bytes) to block transfer (max 64K bytes). mtd_speedtest shows that write throughtput increases : - from 734 to 782 KiB/s (~6.5%) with s25fl512s SPI-NOR. - from 4848 to 5319 KiB/s (~9.72%) with Micron SPI-NAND.
