[PATCH v3] board: apalis-tk1: launch toradex easy installer in usb recovery

[Marcel Ziswiler]

From: Marcel Ziswiler <marcel.ziswiler at toradex.com>

The USB recovery mode is used by Toradex to load the Toradex Easy
Installer image which supports further system images installation.
Prepare for loading and launching the Toradex Easy Installer if the
USB Recovery mode is activated.
