I tried separating it into two initializations and do as much as
possible in the platform driver but because the TCB clocks are
peripheral clocks that depend on most of the other ones, I didn't find
it convenient. This can safely be changed to CLK_OF_DECLARE. I can send
v4 if you want. This should probably be changed for the other drivers
too.
