[PATCH linux dev-6.6 5/5] pinctrl: aspeed-g6: Add NCSI pin group config

[Potin Lai]

Based on the NCSI pin table (Table 181) in NCSI spec[1], the reference
clock output pin (RMIIXRCLKO) is not needed on the management controller
side.

To optimize pin usage, add new NCSI pin group that excludes RMIIXRCLKO,
reducing the number of required pins.
