I'm fine either way, AFAICS it is a matter of setting parent of just
one clock - "mout_mx_mspll_ccore". The driver needs to get that clock
anyway to enable/disable it as required. So we will not gain much from
using assigned-clocks I'd say. I don't really have a strong opinion here
as I don't know detailed requirements of the DMC clock configuration
sequence. I'm inclined to keep it in driver as it would be more flexible.
