Add u-boot enviroments to support distro boot which scan boot.scr from external storage devices (e.g. SD/USB/SCSI disk) and execute autoboot script
Signed-off-by: Priyanka Jain priyanka.jain@nxp.com --- Depends on https://patchwork.ozlabs.org/patch/990094/ Changes for v3: Add USB as boot target device
Changes for v2: xspi_bootcmd, sd_bootcmd env variables are dependent on board. So, move the definition from lx2160a_common.h file to lx2160ardb.h file
