Split the SM platform device into separate platform devices for PM, RTC, WDT and EIC. This is more correct according to the documentation and allows us to simplify the code a little. Also turn the EIC driver into a real platform driver. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com> Acked-by: Hans-Christian Egtvedt <hcegtvedt@atmel.com>
