pinctrl: airoha: fix wrong PHY LED mux value for LED1 GPIO46

In all the MUX value for LED1 GPIO46 there is a Copy-Paste error where
the MUX value is set to LED0_MODE_MASK instead of LED1_MODE_MASK.

This wasn't notice as there were no board that made use of the
secondary PHY LED but looking at the internal Documentation the actual
value should be LED1_MODE_MASK similar to the other GPIO entry.

Fix the wrong value to apply the correct MUX configuration.
