description:
  The clock architecture in Mediatek like below
  PLLs -->
          dividers -->
                      muxes
                           -->
                              clock gate

  The apmixedsys provides most of PLLs which generated from SoC 26m.
  The topckgen provides dividers and muxes which provide the clock source to other IP blocks.
  The infracfg_ao and pericfg_ao provides clock gate in peripheral and infrastructure IP blocks.
