arm: at91/spl: mpddrc: add struct atmel_mpddrc_config
Add struct atmel_mpddrc_config to accommodate the mpddrc register configurations, not using the mpddrc register map structure, struct atmel_mpddrc, in order to increase readability and reduce run-time memory use. Signed-off-by: Wenyou Yang <wenyou.yang@atmel.com> Reviewed-by: Andreas Bießmann <andreas.devel@googlemail.com>
