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

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
