By default these clocks are children of pll_m, but in downstream kernels
they are reparented to pll_c. While at it, decrease their frequencies to
300 MHz because the defaults aren't in the specified range.
gr2d can reportedly run at much higher frequencies, but 300 MHz works
and is a more conservative default.
