mips: lantiq: add support for clk_get_parent()

Browse Source 
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: 171bb2f19e ("MIPS: Lantiq: Add initial support for Lantiq SoCs")
