Most callers of arm_setup_stack substract a fixed offset of 8, 12 or 16
bytes from the stack top. This is unnecessary as on ARM we have a stack
that decrements before storing values. Substracting this offset probably
goes back to the U-Boot version we forked from. Stop this now.

The socfpga xload images are limited to 64KiB. This doesn't fit if
multiple boards are selected. The reason is that we include huge
C files and arrays in the early init code which get compiled once
for each board. -ffunction-sections is without effect here since all
functions have the same name and hence we get the same function
multiple times in the same section.
To overcome this we surround all function names with a SECT() macro which
is used to add a board specific prefix to the section names. This way
-ffunction-sections can now do its work and discard unused functions.

Apart from the RAM size, all cyclone5-based Socfpga boards use the
same lowlevel code. Instead of duplicating it for every board, move
it to mach-socfpga and provide a macro to use it in the boardspecific
code.
