Michael Hennerich 331693129d Blackfin arch: Fix Bug - Kernel does not boot if re-program clocks 
On BF561 EBIU_SDGCTL bit 31 controls the SDRAM external data
path width, typically set 0 for a 32-bit bus width. On other
Blackfin derivatives this bit should be set by default.

Michael Hennerich 73feb5c09d Blackfin arch: fix bugs and unify BFIN_KERNEL_CLOCK option 
- remove duplicated code and headers
 - add option allowing arbitrary SDRAM/DDR Timing parameters.
 - mark automatically calculated timings as EXPERIMENTAL
 - fix comment header block

Related to BUGs:
 - kernel boot up fails with CONFIG_BFIN_KERNEL_CLOCK item on.
 - kernel does not boot if re-program clocks

[ Mike Frysinger <vapier.adi@gmail.com>
 - fix comment header
 - mark do_sync static
 - document the DMA shutdown
 - simplify SIC_IWR handling
 - fix ANOMALY_05000265 handling to work as intended ]
