thermal/drivers/int340x/processor_thermal: Fix tcc setting
commit fe6a6de6692e7f7159c1ff42b07ecd737df712b4 upstream.
The following fixes are done for tcc sysfs interface:
- TCC is 6 bits only from bit 29-24
- TCC of 0 is valid
- When BIT(31) is set, this register is read only
- Check for invalid tcc value
- Error for negative values
Fixes: fdf4f2fb8e899 ("drivers: thermal: processor_thermal_device: Export sysfs interface for TCC offset")
