arm64: dts: meson-gx: Make mmc host controller interrupts level-sensitive

stable inclusion
from stable-v5.10.168
commit 809f4acb7f015e087c60ea74b935e24a16779b0a
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I7URR4

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=809f4acb7f015e087c60ea74b935e24a16779b0a

----------------------------------------------------

commit 66e45351 upstream.

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.
