[PATCH V5 08/20] ARM: dts: stm32: Repair SDMMC1 operation on AV96

[Marek Vasut <marex@denx.de>]

The SD uses different pinmux for the D123DIRline, use such a pinmux,
otherwise there is a pinmux collision on the AV96. Add missing SD
voltage regulator switch.

V2: Disable SDR104, it seems unstable thus far
V3: No change
V4: Rebase on stm32-next
V5: Reorder this patch after the PMIC patches
