pinctrl: airoha: fix I2C pin mux config for AN7583

Browse Source 
On AN7583 both I2C busses have a pin sharing with GPIO. Also the pin mux
setting is done in REG_GPIO_PON_MODE instead of REG_GPIO_2ND_I2C_MODE.

Add dedicated I2C pin groups and function groups for AN7583. The new
groups must support i2c0 and i2c1.
