u-boot-zynq-scr.bb: Recipe to create u-boot.scr for Xilinx devices

Xilinx u-boot supports distrocmd, this required u-boot.scr from distro
to provide the required default boot instead of scanning through the
list of available boot devices.

This patch enables SD boot mode by default for ZU+ and Versal devices.
