[PATCH 3/4] arm: omap: am33xx_generic: fix DDR setup for DDR2

[Jan Luebbe]

For DDR2 RAMs, regs->zq_config is not used, which causes the
AM33XX_EMIF4_0_REG(SDRAM_CONFIG) register to be left unconfigured, resulting
in boot failure.

It seems that the DDR2 case was missed during the consolidation in commit
9f122f8bf023a12ad5f84b61d1d74d3ff06104dd. The actual call for the Bone was
removed in 88659d9c4a87a730f6efe4f38c011e8e0214a67b.

I've tested this on White and Black BeagleBones. An additional test on the
PCM051 would be good.
