patch_saveenv

This patch removes the hardcoded device for env location and set the variable
bootdevice to 0 (i.e. the SD card) to the default env.
This makes u-boot saves the env file according to bootdevice instead of
hardcoded one (now the SD card) when using the saveenv command.

This is an enhancement for users who boot from eMMC and don't affect users of
SD card only.

It also correct the SetupUenv command to load u-boot.env (the filename of the
saved end) instead of uEnv.txt.

Note that currently u-boot fails to correctly saves the env to a FAT12
partition, you must use a FAT16 one.
You can create a correct bootable FAT16 partition for the eMMC like this when
booting from SD card :

gpart destroy -F mmcsd1
gpart create -s mbr mmcsd1
gpart add -t fat16 -b 4096 -s 10M
gpart set -a active -i 1 mmcsd1
newfs_msdos -F 16 -h 4 -u 16 -S 512 -m 0xf8 -n 2 -c 4 -a 20 -r 4 -e 512
/dev/mmcsd1s1

Cheers,
