Modify configuration for Tezi:
- Enable SDP in U-Boot
- Enable FDT relocation (in-place is causing issues with FIT images)
- Remove video output
- Boot from external SD cards using distroboot first by default
- Disable USB PID from config block (otherwise recovery mode download
in U-Boot stage fails)

Just like the following commit for distro boot also use the 2nd instance
for legacy sdboot:

Currently distro boot is only used for external media. Use mmc 1
which is the external SD card when booting using distro boot.

Store U-Boot environment in eMMC, before config block at the end of 1st
"boot sector".

Use proper emmc specific device tree and boot from eMMC by default
rather than from NAND aka ubi.

The kernel does not know about rw,noatime. The string rw by itself
is valid, and to pass additional arguments rootflags=noatime can
be used. The kernel mounts ext3/ext4 file systems by default ro,
hence so far the kernel mounted the rootfs read-only. The init
manager systemd then remounts the rootfs after file system checking.
This makes sense and does not add measureable boot time. Let the
kernel explicitly mount ro on block device based rootfs.
The root mount flag noatime is only relevant when re-mounting
read-write, hence it needs to be present in /etc/fstab.
UBIFS used on raw NAND devices has no user space file checking,
hence there is no value to mount it in read-only first. Also mount
time for UBIFS is larger, and mounting first read-only and then
read-write has higher boot time (300ms, likely due to missing block
cache). Let the kernel explicitly mount rw on raw NAND based rootfs.
UBIFS has no atime support, hence no root mount flags needed.

This adds support for Colibri iMX7 Dual 1GB modules which come
with on-board eMMC storage (whereas the other Colibri iMX7
modules use raw NAND). A subselection (variant) for the
Colibri iMX7 target is used to maximize sharing.
