The board_boot_order() function currenly assumes that the boot source
is MMC/eMMC, but this isn't true for the NAND devices.

This patch cleans up board_boot_order() to check for NAND, SD, ESD,
MMC or EMMC.  Anything beyond these are not supported, so it will
default back to the serial downloader if any of those devices are not
available.

U-Boot binary has grown in such a way that it goes beyond the reserved
area for the environment variables.

Running "saveenv" followed by a "reset" causes U-Boot to hang because
of this overlap.

Fix this problem by increasing the CONFIG_ENV_OFFSET size.

Also, in order to prevent this same problem to happen in the future,
use CONFIG_BOARD_SIZE_LIMIT, which will detect the overlap in build-time.

CONFIG_BOARD_SIZE_LIMIT does not accept math expressions, so declare
CONFIG_ENV_OFFSET with its direct value instead.

- dwc3 and cdns3 bug fixes

- Fix phy_connect() call in two drivers
- fw_setenv bugfix

DWC3 support phy interfaces like 8/16-bit UTMI+. phy interface
initialization code would handle them properly along with UNKNOWN
type by default if none of the user/board doesn't need to use the
phy interfaces at all.

The current code is masking the 8/16-bit UTMI+ interface bits globally
which indeed effect the UNKNOWN cases, therefore it effects the platforms
which are not using phy interfaces at all.

So, handle the phy masking bits accordingly on respective interface
type cases.

In the case where one deletes an already-non-existing variable, or sets
a variable to the value it already has, there is no point in writing the
environment back, thus reducing wear on the underlying storage
device.

In the case of redundant environments, if the two environments
differ (e.g. because one is corrupt), make sure that any call of
fw_setenv causes the two to become synchronized, even if the fw_setenv
call does not change anything in the good copy.
