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 at 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
