colibri_vf: migrate fec, esdhc, nfc and usb to driver model
Migrate FEC, ESDHC, NFC and USB to driver model.
While at it also do no longer enable optional I2C clock in board file as
the generic clock code now handles this. Note for space reason and as
it is not required just for booting we do not enable I2C in U-Boot by
default.
While at it also update copyright period.

ARM: dts: colibri_vf: update device trees
Update device tree in preparation of further driver model migration:
Ethernet FEC, ESDHC aka MMC/SD card, I2C, NFC aka NAND flash controller,
USBH_PEN GPIO regulator.
Add iomux resp. pinctrl entries to be removed from proprietary platform
data: DSPI, ESDHC, FEC, I2C, NFC, UART, USBH_PEN GPIO.
Introduce a U-Boot specific device tree with some required
u-boot,dm-pre-reloc properties: soc, aips0, pinctrl_ddr and uart0 incl.

configs: move CONFIG_MXC_OCOTP to Kconfig
While commit 3e020f03e94f ("driver: misc: add MXC_OCOTP Kconfig entry")
introduced a Kconfig entry it did not actually migrate all
configurations to using it.
As CONFIG_MXC_OCOTP was in mx{6/7}_common.h enable it by default on
those architectures. Additionally, also enable it on ARCH_IMX8M and
ARCH_VF610 where all current members enabled it through their legacy
configuration header files.
Extend the driver to build with DM_VIDEO enabled. DTS files
must additionally include 'u-boot,dm-pre-reloc' property in
soc and ipu nodes to enable driver binding to ipu device.

board: colibri_imx6: check for and report ecc errors in fuses
The PMIC on the Colibri iMX6 may have ECC errors in fuses that will
prevent correct settings. Up to one bit error per fuse bank can be
reported and corrected by the ECC logic. Two bit errors can only be
reported.
RGMII_RD1 pin (active high, GPIO6_IO27) is triggered on reboot during
the SPL phase. This asserts (active low) nReset_Out from the PMIC.
Only V1.1 and later Colibri iMX6 modules implement this in hw. Previous
versions do not use this pin, so it is safe to leave it enabled at all
times.

colibri_imx6: use SDP if USB serial downloader has been used
In case USB serial downloader has been used to load U-Boot start the
serial download protocol (SDP) emulation. This allows to download
complete images such as Toradex Easy Installer over USB SDP as well.
This code uses the boot ROM provided boot information to reliably
detect USB serial downloader.

We have two commands to change the bootmode fuses:
mfgr_fuse which set fuse 0/5 and 0/6
and
updt_fuse which burns bit 4 of 0/5.
Before Image 2.6 we fused in mfgr_fuse 0x5062, which boots
from the user partition of the eMMC.
To workaround certain hangs we moved to fastboot mode and
using the first bootpartition of the eMMC requiring a fuse
value of 0x5072 which could be achived by the then added
updt_fuse command. At the same time the mfgr_fuse command
was changed to also fuse 0x5072, revert that second change
so that one can fuse both values, one with just mfgr_fuse
and the later with mfgr_fuse;updt_fuse.
Note that the mfgr_fuse command is only needed at module
production time, a customer might need to use updt_fuse
when upgrading an older module to be compatible with a
newer image. The command is integrated into the image
update scripts.
