[ Upstream commit a0753ef66c34c1739580219dca664eda648164b7 ]
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.
