mvebu cleanup for 4.4 (part 2)

Remove code related to Armada 375 Z1 stepping no more supported in mainline

This is not needed anymore. Handling a potentially pending imprecise
external abort left behind by the bootloader is now done in a slightly
safer way inside the common ARM startup code.

[gregory.clement@free-electrons.com: Beside the Armada 375 Z1 which
initially required this, is no more supported]
