arm64: dts: imx8mp-debix-model-a: Correct PAD settings for PMIC_nINT

With commit 5d0efaf47ee90 ("regulator: pca9450: Correct interrupt type"),
there is interrupt storm for i.MX8MP DEBIX Model A. Per schematic, there
is no on board PULL-UP resistors for GPIO1_IO03, so need to set PAD
PUE and PU together to make pull up work properly.
