zynqmp: Save "bootseq" environment variable in decimal format

In U-Boot, most of mmc releated commands uses decimal value in arguments, like
"mmc dev ${bootseq}" or "bootargs=root=/dev/mmcblk${bootseq}p2". In order to
improve compatibilities, export "bootseq" number to environment variable in
decimal format instead of hex.
