After this change it is possible to use imx28-<board>-u-boot.dtsi with
the imx28-u-boot.dtsi explicitly included without breaking setup from
imx28-<board>.dts file.
The problem is that the imx28.dtsi included in a wrong place overrides the
changes made in imx28-<board>.dts. As a result some devices are "disabled"
in the final DTB.

This change tries to fix the following problem:
- The board boots (to be more precise - ROM loads SPL) from a slow SPI-NOR
memory.
As a result the spl_boot_device() will return SPI-NOR as a boot device
(which is correct).
- The problem is that in 'falcon boot' the eMMC is used as a boot medium to
load kernel from its partition.
Calling spl_boot_device() will break things as it returns SPI-NOR device.
To fix this issue the new CONFIG_SPL_FORCE_MMC_BOOT Kconfig flag is
introduced to handle this special use case. By default it is not defined,
so there is no change in the legacy code flow.

This commit updates the display5_factory_defconfig file after the switch
to DM/DTS for this board.
Moreover, the VID and PID for SPL running SDP gadget have been updated to
allow seamless work with 'uuu' utility from NXP (the imx_usb doesn't work
properly after embedding the u-boot proper into fitImage - problem with IVT
embedding in FIT).
Example to use 'uuu' session:
cat << EOF > display5_recovery.lst
uuu_version 1.2.135
SDP: boot -f /srv/tftp/SPL
SDPU: write -f /srv/tftp/u-boot-dtb.img -addr 0x10000000
SDPU: jump -addr 0x10000000
SDPU: done
EOF
sudo ./uuu/uuu display5_recovery.lst

This commit enables support for CONFIG_WDT in the U-Boot proper. Moreover,

As SPL is not yet ready for DM conversion, the CONFIG_HW_WATCHDOG is
enabled for it. This allows the legacy SPL code to work properly.

U-Boot binary has grown in such a way that it goes beyond the reserved

Fix this problem by increasing the CONFIG_ENV_OFFSET size.
Also, in order to prevent this same problem 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
