colibri_vf: add distroboot support
Add support for distro boot. This is especially helpful for external
devices. There is a global boot command which scans a predefined
list of boot targets:
run distro_bootcmd
As well as direct boot commands such as:
run bootcmd_mmc0
run bootcmd_usb
run bootcmd_dhcp
...
Refer to doc/README.distro fo details.
While at it also re-order boot command macros as well as the
CONFIG_EXTRA_ENV_SETTINGS.
