[PATCH v5 01/22] at91: mmccpu: remove board support for mmccpu

[Sam Ravnborg <sam@ravnborg.org>]

Based on feedback from Sascha:
http://lists.infradead.org/pipermail/barebox/2018-January/031796.html
"
Let's just remove this board
instead of ventilating it any further.
"

Remove mmccpu board - and all references to this board.
