arm64: dts: meson-axg: Make mmc host controller interrupts level-sensitive
The usage of edge-triggered interrupts lead to lost interrupts under load, see [0]. This was confirmed to be fixed by using level-triggered interrupts. The report was about SDIO. However, as the host controller is the same for SD and MMC, apply the change to all mmc controller instances.
