The Microchip MPFS Icicle Kit uses Cadence SD/SDIO/eMMC Host Controller
without any additional vendor compatible:

I think the lack of vendor compatible is the error here. Experience has
shown that vendor specific compatibles are needed for licensed IP.

In such case this could be:
1. a specific "microchip,mpfs250t-sd4hc", which
seems to be on MPFS Icicle Kit:

2. or a generic "microchip,mpfs-sd4hc"

Any hints here?

Best for a Microchip person to answer, but sure there's some existing
compatible strings for other blocks on this chip to follow the same
pattern.
