The 3430SDPs, many of which use Qimonda SDRAM, are finally using
bootloaders that program rounded rates for DPLL3.  Since no SDRAM
memory timings are defined for the rounded rates, the initial SDRC
reprogram during init fails.  Add in the correct timings here.

Problem reported by Kevin Hilman <khilman@deeprootsystems.com>.
