tegra: seaboard: disable SPI, move environment to eMMC
The SPI hardware on Seaboard is too broken to use; it is muxed with the
console UART and requires evil interactions between the SPI and UART
drivers to work even partially. The current code in U-Boot is not
sufficient to make this work correctly; auto boot is aborted due to
corruption in the UART RX channel interrupting it.
Instead, move the environment to eMMC, at the end of the second boot
sector. This should not conflict with any other eMMC usage, irrespective
of whether the board boots from SPI, NAND, or eMMC: if U-Boot is stored
in eMMC, it will be stored well below this location. The kernel only
uses the general area of the eMMC once booted, not the boot sectors.
Boards that are derivatives of Seaboard don't have the muxing issue,
and should/could have a separate U-Boot configuration file that does
enable SPI if desired.
Alternatively, the environment could be stored in NAND flash, but we
currently have no driver for that controller.

tegra: flesh out bootcmd
This implements a useful bootcmd for Tegra. The boot order is:
* If USB enabled, USB storage
* Internal MMC (SD card or eMMC)
* If networking is enabled, BOOTP/TFTP
When booting from USB or MMC, the boot script is assumed to be in
partition 1 (although this may be overridden via the rootpart variable),
both ext2 and FAT filesystems are supported, the boot script may exist
in either / or /boot, and the boot script may be named boot.scr.uimg or
boot.scr.
When booting over the network, it is assumed that boot.scr.uimg exists
on the TFTP server. There is less flexibility here since those setting
up network booting are expected to need less hand-holding.
In all cases, it is expected that the initial file loaded is a U-Boot
image containing a script that will load the kernel, load any required
initrd, load any required DTB, and finally bootm the kernel.
