[RFC] sanitizing crazy clock data files

[Sascha Hauer]

The following tries to solve the chicken-egg problem we have with the
common struct clk support and its users. It switches i.MX51 clock support
to the new API. Included are some generic clock helpers for dividers and
multiplexer. I first made them i.MX specific but after looking round in
the other architectures I found them useful enough for other architectures
aswell. If you could use the helpers but missing some bits please speak up.

There is one thing missing in Jeremys series and this series does not fix
it. Once I add the new (un)prepare calls to drivers they won't compile
without common struct clk support anymore. Maybe a

#ifndef CONFIG_USE_COMMON_STRUCT_CLK
#define clk_prepare()
#define clk_unprepare()
#endif

will do.
