[PATCH] thermal/drivers/airoha: Fix low trip clamp using wrong variable

["Wayen.Yan" <win847@gmail.com>]

In airoha_thermal_set_trips(), the low trip validation incorrectly
clamps 'high' instead of 'low':

  low = clamp_t(int, high, RAW_TO_TEMP(priv, 0), ...);

This causes TEMPOFFSETL to receive the clamped high-temperature value
instead of the requested low-temperature value, making the low-temperature
alert threshold identical to the high-temperature threshold. As a result,
low-temperature interrupts can never fire independently.

Fix by replacing 'high' with 'low' in the clamp expression, matching
the symmetric pattern used for the high trip on line 264.
