Adjust Tegra's default boot scripts to use the correct location. This change aligns Tegra's boot scripts with rpi_b.h and also the location that the Fedora installer actually puts the file.

On ARM at least, some parts of high memory are "highmem" and can't be accessed at early boot. To solve this, we need to restrict this relocation process to use lower parts of RAM that area accessible. For the DTB, an earlier patch of mine set CONFIG_SYS_BOOTMAPSZ. However, since some platforms have different restrictions on DTB and initrd location, that config option doesn't affect the initrd. We need to set the initrd_high environment variable to control the initrd relocation. Since we have carefully chosen the load addresses for the DTB and initrd (see comments in include/configs/tegraNNN-common.h re: values in MEM_LAYOUT_ENV_SETTINGS), we don't actually need any DTB or initrd relocation at all. Skipping relocation removes some redundant work. Hence, set both fdt_high and initrd_high to ffffffff which completely disables relocation. If the user does something unusual, such as using custom locations for the DTB/initrd load address or wanting to use DTB/initrd relocation for some reason, they can simply set these variables to custom values to override these environment defaults. With this change, cmd_sysboot works correctly for a filesystem created by the Fedora installer.
