These clocks are required for usb operation. pll_p_out4 needs to be set
to 24 MHz. The other clocks default to "off" in order to save some energy.

Given the rest of the thread, this is fine for now. We can address any
deficiencies in the bus clock and clk_m parenting when it's addressed
globally for all boards later.
