[PATCH v2 0/2] arm64: dts: st: add eMMC support on STM32MP257F-DK

This series enables the eMMC of the STM32MP257F-DK.

The sdmmc2 node and the _a pin groups are already in stm32-next. On
this board, the _a groups give corrupted reads in HS200 mode at 100 MHz
without any CRC error. Patch 1 adds _b groups with the faster output
speeds that the datasheet gives for 120 MHz and 166 MHz operation, and
patch 2 enables the eMMC with them.

Changes in v2:
- Rebased on stm32-next, the sdmmc2 node and _a pins are already there
- Dropped the patches adding them
- Added _b pin groups with faster output speeds
- Dropped the vddio2 regulator range, VDDIO2 is tied to 1V8 on the DK
