ARM: omap3_logic.c: Optimize DDR timings based on OMAP35 or 36/37

The default timings are assumming an OMAP36 / AM37 / DM37, but
the OMAP35 controller is a bit slower, so DDR may operate out of
spec when under stress.  This patch checks the processor type and
sets the DDR timings according to processor type.

Fixes: 5ad4212ce0d5 ("ARM: DTS: Add Logic PD OMAP35/DM37 SOM-LV
and OMAP35 Torpedo")
