brppt1: Update environment to support new boot concept
* Drop legacy /boot/PPTImage.md5 check
* Update device tree naming
* Update t30args#0 root cmd line property to support latest kernel
versions (root=/dev/mmcblk0p2 for linux < 4 and
root=/dev/mmcblk1p2 for linux >= 4)
* Add custom bootloader version string
* Destroy invalid dtb at ${dtbaddr} and configuration script at
${cfgaddr} to ensure proper boot in warm restart case.
