[PATCH v3 01/24] mmc: sdio: add SDIO IDs for Silabs WF200 chip

[Jerome Pouiller]

From: Jérôme Pouiller <jerome.pouiller@xxxxxxxxxx>

Add Silabs SDIO ID to sdio_ids.h.

Note that the values used by Silabs are uncommon. A driver cannot fully
rely on the SDIO PnP. It should also check if the device is declared in
the DT.
