Replace CONFIG_ENTROPY_NAME with DT_CHOSEN_ZEPHYR_ENTROPY_LABEL. We now set zephyr,entropy in the chosen node of the device tree to the entropy device. This allows us to remove CONFIG_ENTROPY_NAME from dts_fixup.h. Also remove any other stale ENTROPY related defines in dts_fixup.h files. Signed-off-by: Kumar Gala <kumar.gala@linaro.org>
