board: atmel: clean up peripheral clock code
Due to introducing the new peripheral clock handle functions, use these functions to reduce duplicated code. Signed-off-by: Wenyou Yang <wenyou.yang@atmel.com> Tested-by: Heiko Schocher <hs@denx.de> [Rebased on current master, fixup for at91rm9200ek] Signed-off-by: Andreas Bießmann <andreas.devel@googlemail.com>
