configs/versal_vek280_defconfig: new defconfig

This patch adds support for Xilinx Versal VEK280 Evaluation Kit.

VEK280 features can be found here:
https://www.xilinx.com/products/boards-and-kits/vek280.html

The VEK280 requires a patch for the memory node in the dts file because it is
not currently correct.  This patch has been applied to the linux-xlnx repo and
will be included in the 2024.2 release.

+Subject: [PATCH] arm64: versal: Fix vek280 memory configuration
+
+Board has 12GB total but Vivado wizard supports one channel LPDDR4 4GB
+configuration (2GB low + 2GB high) or two channel LPDDR 8GB configuration
+(2GB low + 6GB high). Wiring the remaining 4GB LPDDR can be done via board
+tab but not available as option in wizard. That's why only describe 8GB by
+default.
