mach-netx had its own implementation of clk routines like, clk_get{put},
clk_enable{disable}, etc. And with introduction of following patchset:
https://lkml.org/lkml/2012/4/24/154
we get compilation error for multiple definition of these routines.
Sascha had following suggestion to deal with it:
http://www.spinics.net/lists/arm-kernel/msg179369.html
So, remove this code completely.
