Hi Gregory, sorry I wasn't sure if I should resend the patch.

Boot hangs on EspressoBIN Ultra (Armada 3720) after a message that device
vcc_sd1 had been disabled. The device manufacturer patched this issue in
their kernel fork noting that vcc_sd1 is used by the EspressoBIN model
but not the EspressoBIN Ultra. Removing the device from the tree fixes
the boot hang and wifi.
