exynos5420: add a peripheral clock select --> PLL decoder

This adds a helper function to translate between peripheral clock
    select fields in clock source registers and PLLs. Some of this was
    already done to handle a few special cases, this generalizes the
    earlier work so that follow-up patches can do further clean-up.

Unfortunately, the PLLs represented by clock select fields in
    various modules are not uniformly ordered. So for now we focus on
    peripheral clock sources only.
