cpu/atmega*: remove unnecessary code (already factored out)

cpu.c and startup.c were redundant in most platforms, except for atmega256rfr2. The common code is now in cpu/atmega_common/cpu.c and cpu/atmega_common/startup.c. cpu_conf.h is also removed as it's now in cpu/atmega_common/include thus shared by all atmega based platforms.
