pinctrl: airoha: fix I2C pin mux config for AN7583

This commit adds dedicated I2C pin groups and function groups for AN7583.
It introduces new groups to support both i2c0 and i2c1 because both busses
share pins with GPIO.

[Severity: Medium]
Will this addition cause device tree validation failures?

Looking at Documentation/devicetree/bindings/pinctrl/airoha,an7583-pinctrl.yaml,
the schema strictly limits the "i2c" function's valid groups to only "i2c1":

          - if:
              properties:
                function:
                  const: i2c
            then:
              properties:
                groups:
                  enum: [i2c1]

If a user specifies function = "i2c" and groups = "i2c0" in a board device
tree, it will fail dtbs_check schema validation, despite being valid and
supported by the updated driver.

Should the device tree binding document be updated alongside this change to
allow the new "i2c0" group?
