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

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
