board_init_lowlevel is no longer called from generic code, so we can't
just return from in. Instead we have to jump to board_init_lowlevel_return
manually. For the a9m2440 board one case was missed to convert. This
is broken since:

| ARM: give boards control of the reset entry point
|
| On some SoCs (for example AM35xx), the ROM bootloader passes useful
| information in r0 when jumping to barebox.
|
| To avoid overwriting this in the generic reset code, we introduce
| common_reset as a C function and as an assembler macro. This is then
| called form the reset entry point (either in common or in board code).
|
| This patch is based on code by Sascha Hauer <s.hauer at pengutronix.de>.
