I'll just re-intereate my comment on why not have the structure
with a single rate and a single register value? I'd also prefer
to see it as a structure instead of an array, ie:
struct s5p_epll_speed {
unsigned int speed;
unsigned int con;
};

let's look at putting these in arch/arm/plat-samsung/include/plat
as iirc we've actually already got a branch wehere we move this pll
