Oops, WHPLL sits behind the gate, so the clock tree is this:
- mfgcfg
  ^- mfg_pre ('safe' UNIVPLL div or 'unsafe' mfg mux)
     ^- mfg (if you're here and your chip is NOT mt6572w then be prepared
             for crashes)
        ^- mfg_pre_whpll_500m (or any other parent, but downstream uses
                               WHPLL as GPU clock source)
           ^- whpll

(Using 500m is a bad idea for the PLL which can change frequency, but
I have to revisit clock tree once again to make a better decision before
sending mt6572 clocks to the upstream).
