Merge branch 'mvebu/drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Merge the mvebu/drivers branch of the arm-soc tree which contains
just a single patch bfa1ce5f38938cc9e6c7f2d1011f88eba2b9e2b2 ("bus:
mvebu-mbus: add mv_mbus_dram_info_nooverlap()") that happens to be
a prerequisite of the new marvell/cesa crypto driver.
