What is the release version you are using? I remember max-clk-limit has already been removed from Nano dts for quite long.
The device tree is also wrong. Lacking of cd-gpio and vmmc-supply. That makes you not able to remove the max-clk-limit.
For old release <=32.2. Below thread includes the need.
And this thread is for rel-32.5.1 that was just done last week.
