Move the shared environment from CFG_EXTRA_ENV_SETTINGS in
mx6sabre_common.h to a common text environment fragment in
include/env/nxp/mx6sabre_common.env. The mx6sabresd and mx6sabreauto
board environments include this fragment and add their own console
setting, which is the only board specific difference between them. The
eMMC firmware update variables remain guarded by CONFIG_SUPPORT_EMMC_BOOT
inside the fragment. The now unused CONSOLE_DEV defines and the
linux/stringify.h include are dropped.

The generated default environment is unchanged for both boards. This was
verified by comparing the output of scripts/get_default_envs.sh before
and after the change, which produced identical results.

Caleb Ethridge <caleb.ethridge@analog.com> says:

This series performs a general cleanup of the default U-boot environment
for sc5xx boards, stemming from the decision to no longer store the
environment in the SPI flash. The environments for each board have been
edited to contain the minimum number of commands needed for all supported
boot modes to avoid confusion, and the default boot command synced to spi
for all boards that support it. The filesystem for the SPI flash has also
been changed from jffs2 to ubifs.

A bug with the Ethernet reset line on the sc594 has been fixed, and the
sc573 has been renamed from the EZKIT to the EZLITE to match the name of the
publically available board. EZKIT was only used internally before release.
Preliminary binman support for sc5xx boards has been removed as it was unused
and full support never added.

Remove the SC5XX_LOADADDR Kconfig option, replace its users with
CONFIG_SYS_LOAD_ADDR, and update the ADI boot environment to use
`loadaddr`.

SC5XX_LOADADDR was an ADI-specific duplicate of standard U-Boot
load address handling. U-Boot already uses CONFIG_SYS_LOAD_ADDR
for the default load address and `loadaddr` for boot commands,
so keeping separate SC5XX-specific names is redundant.

Update the bootargs used in SPI/OSPI bootmode
to reflect change from jffs2 to ubifs for the
SPI's filesystem, and remove the jffs2file variable
from the environment as it is now unused.

Switch the nfsboot and other relevant commands to use
wget instead of tftp. This also includes the addition of
the httpdstp variable for selecting the wget port.

There is no longer any automatic DHCP configuration. Before
running a command with wget, either 'dhcp' must be run or
the 'ipaddr' and 'serverip' variables must be set. Additionally,
the nfsboot command looks for the file named 'fitImage' on the
server to use to boot.

The default port is set to 8000 instead of the usual 80
to allow for use with an unprivileged web server.

Update the default boot commands to match the expected
bootargs in Linux and new SPI partitioning scheme.

Because the environment is no longer stored in the SPI
flash, imagesize has been removed and replaced with a fixed
length read to load from the SPI. Additionally the partitions
of the mmc have been updated. The first partition holds the fitImage
at /fitImage, and the second partition contains the rootfs.
With this change, the imagefile environment variable has also been
eliminated, the image in the first partition is expected to always
be named fitImage.

Remove the update_spi family of commands from the U-Boot
environment. These commands are not standard in U-Boot,
and boot media programming has moved to Linux, so the
commands can be safely removed.

Additionally, this commit removes the adi_stage2_offset,
adi_rfs_offset, imagefile, jffs2file, and init_ethernet variables that
were consumed by the update commands as they are no longer needed.
CONFIG_SC5XX_UBOOT_OFFSET and CONFIG_SC5XX_ROOTFS_OFFSET are also
removed.
