mips: lantiq: add support for clk_get_parent()
[ Upstream commit fc1aabb088860d6cf9dd03612b7a6f0de91ccac2 ]
Provide a simple implementation of clk_get_parent() in the
lantiq subarch so that callers of it will build without errors.
Fixes this build error:
ERROR: modpost: "clk_get_parent" [drivers/iio/adc/ingenic-adc.ko] undefined!
Fixes: 171bb2f19ed6 ("MIPS: Lantiq: Add initial support for Lantiq SoCs")
