DM: OMAP24XX_I2C: Reduce overhead when used with OF_PLATDATA

Platforms with limited resources in SPL may enably OF_PLATDATA,
this limits some of the library functions and cannot extract data
from the device tree.  This patch adds additional wrappers around
these functions to only allow them when OF_CONTROL is enabled and
OF_PLATDATA is not.
