Mike Frysinger 74398b23f9 Blackfin: put memory into self-refresh before/after programming clocks 
When initializing the core clocks, stick external memory into self-refresh.
This gains us a few cool things:
 - support suspend-to-RAM with Linux
 - reprogram clocks automatically when doing "go" on u-boot.bin in RAM
 - make sure settings are stable before flashing new version
 - finally fully unify initialize startup code path between LDR/non-LDR
