OK so far.

But what happens when a single kernel is built that has support for an
SoC with an SDRC (OMAP4) and one that doesn't (AM33xx)?

In that case this new SOC_HAS_OMAP2_SDRC will be set, and
set_globals_sdrc() will be called even for the SoCs without SDRC.

So, rather than add a new Kconfig option for this, I would rather see 
you using the existing runtime feature check for the SDRC: omap_has_sdrc()
