Add support for accessing GPIOs using of-plata. This uses the same mechanism as for clocks, but allows use of the xlate() method so that the driver can interpret the parameters. Update the condition for GPIO_HOG so that it is not built into SPL, since it needs SPL_OF_REAL which is not enabled in sandbox_spl. Signed-off-by: Simon Glass <sjg@chromium.org>
