This patch converts the mxsmmc driver to support DM/DTS.
Moreover, it is also possible to use it in early SPL with
SPL_OF_PLATDATA enabled.

After this patch the mxs_spi.c DM/DTS driver can be used at early SPL to
read payload from SPI-NOR memories.
It was necessary to adjust its name to 'fsl_imx_2{38}_spi' to match
requirements for SPL_OF_PLATDATA usage.

Without this change the DM/DTS version of mxs_spi driver doesn't reset the
SPI IP block in probe.
As a result this driver (when used solely on U-Boot proper) relies on reset
performed by mxs spi driver in SPL.
In the use case where eMMC is used in SPL as a boot primary device, the
mxs_reset_block() is not called at all and DM/DTS aware SPI driver in
U-Boot proper is malfunctioning.

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,
the SYSRESET_WATCHDOG driver is used to support 'reset' command.
As SPL is not yet ready for DM conversion, the CONFIG_HW_WATCHDOG is

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