To properly manage SDIO on STM32 variant of PL18x, we cannot have DMA
Linked Lists enable. As it has to be disabled during probe sequence,
we cannot wait until we have communicated with the SDIO chip. This
should then be done through a DT property.
The MMC_PM_KEEP_POWER should also be disabled on STM32MP157x-DK2 board
as the clock used for wifi is not always-on.

  mmc: mmci: manage MMC_PM_KEEP_POWER per variant config
