[PATCH master] mci: stm32_sdmmc2: add STM32MP131 AMBA primecell peripheral ID

[Ahmad Fatoum]

v5.18-rc1 device tree now features different peripheral ID. As
peripheral IDs have no fallbacks, this meant broken SD on STM32MP131.

Add new peripheral ID without special handling as IP is
backwards-compatible. DT also contains a st,stm32-sdmmc2 compatible,
which we could match against in future, but for now this isn't
necessary.

Fixes: b01786baa849 ("dts: update to v5.18-rc1")
