This switches the at91sam926x, 9g10 and 9g20 over to barebox_arm_entry.
For these SoCs we currently support reading back the memory size from
the SDRAM controller, so all of these can have a common reset() function.

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@pengutronix.de>.
