Use DEFAULT_LINUX_BOOT_ENV to define the standard addresses used in rest of TI platforms as defined in ti_armv7_common.h This avoids the standard pitfalls we've had with kernel images and fdt addresses stomping on each other. As part of this process, redefine overlayaddr to be dtboaddr (defined in ti_armv7_common.h for this very purpose) and get rid of the definition of overlayaddr..
