arm: mvebu: introduce common lowlevel and early init

At early stage after boot, all MVEBU SoCs are similar enough to have
a common lowlevel and barebox entry. We  also remap the internal register
base address to 0xf100000 as it gives some 512M more of contiguous address
space. As we cannot determine real memory size that early, we start with
a default memory size of 64M and probe correct size later in SoC init.
