dt: remove of_alias_get_id() reference
of_alias_get_id() is broken and being reverted. Remove the reference to it and replace with a single incrementing id number. There is no risk of regression here on the imx driver since the imx change to use of_alias_get_id() is commit 22698aa2, "serial/imx: add device tree probe support" which is new for v3.1, and it won't get used unless CONFIG_OF is enabled and the board is booted using a device tree. A single incrementing integer is sufficient for now. Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Acked-by: Shawn Guo <shawn.guo@linaro.org>
