Subject: [PATCH v2 3/7] thermal: int340x: processor_thermal: Set feature mask before proc_thermal_add

The function proc_thermal_add() adds sysfs entries for power limits.
The feature mask of available features is not present by this time.
If feature mask is available, then this can be used to selectively
create attributes.

Feature mask is set during call to proc_thermal_mmio_add(). Change the
order of calls so that proc_thermal_mmio_add() is called before
proc_thermal_add().

There is no functional impact with this change.
