[RFC 1/2] clk: use struct clk only for external API

In order to provide per-user accounting, this separates the struct clk
used in the common clock framework into two structures 'struct clk_core'
and 'struct clk'.  struct clk_core will be used for internal
manipulation and struct clk will be used in the clock API
implementation.

In this patch, struct clk is simply renamed to struct clk_core and a new
struct clk is implemented which simply wraps it.  In the next patch, the
new struct clk will be used to implement per-user clock enable
accounting.

There is a rather hacky #define of clk_core to clk for the non-common
clk case in order to avoid a mass rename of all clk non-common clk
implementations.

I like the spirit of this and I think it was Thomas Gleixner who early
on strongly recommended that the struct be kept as private as possible.
