dts: add property removal option CONFIG_OF_REMOVE_PROPS
This can be used for device tree size reduction similar as CONFIG_OF_SPL_REMOVE_PROPS option. Some boards must pass the built-in DTB unchanged to the kernel, thus we may not cut it down unconditionally. Therefore enable the property removal list option only if CONFIG_OF_DTB_PROPS_REMOVE is selected. Signed-off-by: Anatolij Gustschin <agust@denx.de>
