[PATCH v2 2/2] dt-bindings: pinctrl: aspeed,ast2600-pinctrl: add NCSI group

[Potin Lai <potin.lai.pt@xxxxxxxxx>]

In the NCSI pin table, the reference clock output pin (RMIIXRCLKO) is not
needed on the management controller side.

Add NCSI group to distinguish the pin group between RMII and NCSI.

- RMII pins:
  - RMIIXRCLKI
  - RMIIXRXD0
  - RMIIXRXD1
  - RMIIXCRSDV
  - RMIIXRXER
  - RMIIXRCLKO
  - RMIIXTXEN
  - RMIIXTXD0
  - RMIIXTXD1

- NCSI pins:
  - RMIIXRCLKI
  - RMIIXRXD0
  - RMIIXRXD1
  - RMIIXCRSDV
  - RMIIXRXER
  - RMIIXTXEN
  - RMIIXTXD0
  - RMIIXTXD1
