Documentation/core-api: correct reference to SWIOTLB_DYNAMIC

Commit c93f261dfc39 ("Documentation/core-api: add swiotlb documentation")
accidentally refers to CONFIG_DYNAMIC_SWIOTLB in one place, while the
config is actually called CONFIG_SWIOTLB_DYNAMIC.

Correct the reference to the intended config option.
