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.
