thermal/drivers/airoha: Fix AN7583 ADC mux field mapping
On AN7583, bits 3:1 of 0x2e4 select the sensor (0 bandgap, 5 GbE, 6 CPU)
and bits 3:2 of 0x2a0 select the diode (0 D0, 1 ZERO, 2 D1). The driver
names them the other way round: MUX_TADC is 0x2e4, MUX_SENSOR is 0x2a0.
v5 of the AN7583 series swapped the airoha_set_thermal_mux() arguments
to match these names. The diode index now goes to the sensor selector,
so the zone reads mux positions 1, 0 and 2 (PAD_AVS, bandgap, core
voltage) instead of the bandgap diodes. On a Nokia XG-040G-MF the result
crosses the critical trip and the board powers off during boot.
Swap the field definitions. MUX_TADC then selects the diode, as on
EN7581, and the existing call order is correct.
