From: Yann Gautier <yann.gautier at st.com>

Update the IP version to v2.0, which supports linked lists in internal DMA,
and is present in STM32MP1 SoCs.

The mmci driver supports the v2.0 periph id since 7a2a98be672b ("mmc: mmci:
Add support for sdmmc variant revision 2.0"), so it's now Ok to add it into
the SoC device tree to benefit from the improved DMA support.
