clk: ti: LLVMLinux: Move __init outside of type definition

As written, the __init for ti_clk_get_div_table is in the middle of the return
type.

The gcc documentation indicates that section attributes should be added to the
end of the function declaration:

  extern void foobar (void) __attribute__ ((section ("bar")));

However gcc seems to be very permissive with where attributes can be placed.
clang on the other hand isn't so permissive, and fails if you put the section
definition in the middle of the return type:

               ^ ~~~~~~~~~~~~~~~~~~~~~~~~~~
3 warnings and 2 errors generated.

By convention, most of the kernel code puts section attributes between the
return type and function name. In the case where the return type is a pointer,
it's important to place the '*' on left of the __init.

This updated code works for both gcc and clang.
