configs/zynqmp_kria_kv260_defconfig: fix to u-boot.itb generation

Browse Source 
This patch is a temporary fix for the kv260 u-boot.itb generation
until a proper fix has been implemented within u-boot.

The problem is u-boot can only be configured to use the kria k26
som dts configuration at build time, and the kv260 carrier board
overlay is missing from the build.  Without this, all of the carrier
board drivers are missing.

This patch will be removed from buildroot once u-boot can build a
correct u-boot.itb for the kria kv260 starter kit including the
carrier board overlay and corresponding drivers:

# This will be removed when u-boot can build the kv260 u-boot.itb natively.
