Subject: [PATCH 4.4 054/114] mips: lantiq: add support for clk_set_parent()

From: Randy Dunlap <rdunlap@...radead.org>

[ Upstream commit 76f66dfd60dc5d2f9dec22d99091fea1035c5d03 ]

Provide a simple implementation of clk_set_parent() in the lantiq
subarch so that callers of it will build without errors.

Fixes these build errors:

ERROR: modpost: "clk_set_parent" [sound/soc/jz4740/snd-soc-jz4740-i2s.ko] undefined!
ERROR: modpost: "clk_set_parent" [sound/soc/atmel/snd-soc-atmel-i2s.ko] undefined!

Fixes: 171bb2f19ed6 ("MIPS: Lantiq: Add initial support for Lantiq SoCs")
