arm: imx: hab: Add hab_failsafe console command
hab_failsafe when called puts the part into BootROM recovery mode.
This will allow u-boot scripts to script the dropping down into recovery
mode.
=> hab_failsafe
Shows the i.MX7 appear as "hiddev0,hidraw5: USB HID v1.10 Device [Freescale
SemiConductor Inc SP Blank ULT1] " in a Linux dmesg thus allowing download
of a new image via the BootROM USB download protocol routine.
