Since these resets need to be configured in the special sequence, and
these clocks need to be configured with different clock rate.

But the clock instance get, the property name is fixed to "clock-names"
according to the function of_parse_clkspec, and the reset property name
is also fixed to "reset-names" from function __of_reset_control_get.
