Solomon Peachy a6538abd16 rk27xx: Use slower memory timings at startup 
Our decade+old defaults are reported to trigger a failure on
one user's IHIFI770c and IHIFI960, but work on their HM-603.
Backing CAS latency off from 2 to 3 appears to be sufficient.

What's interesting is that on paper, CL=2 should be easily attainable
due to our max RAM clock of 100MHz, well within the worst-case timings
of the EM639165 SDRAM.

So as an experiment, this code can go back to CL=2 when we change the
CPU+RAM clock speeds.  IF this still proves problematic, it will be
removed.
