[PATCH v2 3/3] ARM: dts: stm32mp157a-dk1: overwrite regulator for sdmmc node

[Oleksij Rempel <o.rempel@xxxxxxxxxxxxxx>]

There is currently no driver for the STPMIC1, which supplies the 3v3
rail into the SDMMC2. The regulator is on on boot though, so lets
replace it with a fixed regulator till we have a regulator driver for
the STPMIC1.
