[PATCH 3/5] arm64: dts: st: Reuse sdmmc1_*_pins_a pinmux

[Marek Vasut]

It is perfectly possible to use sdmmc1_*_pins_a on the DH electronics
STM32MP23xx/STM32MP25xx DHCOS SoM, the only difference is the slew rate.
Reuse sdmmc1_*_pins_a with updated slew rate on board level.

Fixes: 9b584c92f94f ("arm64: dts: st: Add support for DH electronics STM32MP23xx/STM32MP25xx DHCOS SoM and Breakout Board and DHSBC")
