The arch/arm/configs/mvebu_*_defconfig currently don't belong to any
maintainer, so get_maintainer returns only information based on
commits, which is not completely accurate.

Therefore, this commit replaces a useless empty newline in MAINTAINERS
by a line attaching those defconfigs to the appropriate Marvell EBU
maintainers.
