SD card is not visible by UEFI
Description of problem:
SD card is not visible by OVMF UEFI, so it's not possible to boot from it:
```
UEFI Interactive Shell v2.2
EDK II
UEFI v2.70 (EDK II, 0x00010000)
Mapping table
     BLK0: Alias(s):
          PciRoot(0x0)/Pci(0x1,0x1)/Ata(0x0)
Press ESC in 1 seconds to skip startup.nsh or any other key to continue.
Shell>
```
It is visible by SeaBIOS though, if we remove the OVMF part from the commandline:
```
qemu-system-x86_64 -device sdhci-pci -drive if=none,file=Fedora-IoT-ostree-41-20241027.0.x86_64.iso,format=raw,id=MMC1 -device sd-card,drive=MMC1
```
