doc: a70x0: a80x0: add secondary recovery image disable description
Armada7k/8k supports secondary image boot when flash stores two images.
However, in order to support secondary image boot, it requires to enable
the option. But this option will interrupt uart recvoery image for A7k and
A8K boards.
This patch adds description for disabling secondary recovery image in
order to build uart recovery image which works well for Armada70x0 and
armada80x0 board.
