[PATCH 1/3] arm64: dts: meson-axg: Make mmc host controller interrupts level-sensitive

[Heiner Kallweit]

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.
