mb/asrock/h110m: disable unused sata ports

Sets all unused sata ports to disable in the device tree

Note:
  SATA4 and SATA5 are located at the bottom of the board, but there
  is no connector for this. Apparently, a board with an increased
  number of ports is very rare. Perhaps this is a separate variant
  of the Asrock motherboard. For this reason, these ports are also
  disabled
