mmc: sdhci-of-dwcmshc: Re-enable support for the BlueField-3 SoC

The commit 08f3dff799d4 (mmc: sdhci-of-dwcmshc: add rockchip platform
support") introduces the use of_device_get_match_data() to check for some
chips. Unfortunately, it also breaks the BlueField-3 FW, which uses ACPI.

To fix the problem, let's add the ACPI match data and the corresponding
quirks to re-enable the support for the BlueField-3 SoC.
