Don't patch patches, replace them.

Have your own bbappend in your own layer which replaces the patch with 
what you need.

A simple

FILESEXTRAPATHS:prepend := "${THISDIR}/${PN}:"

in a bbappend that can be found by BitBake in your layer.

Then add your patch that replaces NXP's patch with yours, in a directory 
next to the bbappend.

Or even better, contact NXP and give them the appropriate patches so 
that you don't have to carry those in your own later.

Cheers,
Quentin
