DM: omap_gpio: Reduce overhead when used with OF_PLATDATA
Platforms with limited resources in SPL may enable 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.
