imx: Introduce CONFIG_SPL_FORCE_MMC_BOOT to force MMC boot on falcon mode
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.
ARM: Update display5_factory_defconfig after switch to DM/DTS and uuu utility
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).

- CONFIG_SPL_FS_EXT4: u-boot-dtb.img is stored in raw sector via dd

CONFIG_MX6_OCRAM_256KB which allows using the full size on boards which
