Commit 08f3dff799d43 introduces the of_device_get_match_data()
checking for some chip but breaks the BlueField-3 firmware which
uses ACPI instead. This commit adds the ACPI match data and
quirks/quirks2 to re-enable the support of BlueField-3 SoC.

v1->v2:
    Fixes an acpi warning
    Reported-by: kernel test robot <lkp@intel.com>
v1: Initial version.

Please re-base this patch because it does not apply to
latest mmc "next" branch.
