CTCaer 792a3511da nyx: clear nand patrol for resized emummc
On used eMMCs, the usage size might exceed the new resized size.
In such cases if the nand patrol points there, it will cause the sd card to timeout because of out of bounds access.

Clearing that allows resized emuMMC to always have the same speed as full sized emuMMC.
