thermal: core: Store trip pointer in struct thermal_instance
[ Upstream commit 2c7b4bfadef08cc0995c24a7b9eb120fe897165f ]
Replace the integer trip number stored in struct thermal_instance with
a pointer to the relevant trip and adjust the code using the structure
in question accordingly.
The main reason for making this change is to allow the trip point to
cooling device binding code more straightforward, as illustrated by
subsequent modifications of the ACPI thermal driver, but it also helps
to clarify the overall design and allows the governor code overhead to
be reduced (through subsequent modifications).
The only case in which it adds complexity is trip_point_show() that
needs to walk the trips[] table to find the index of the given trip
point, but this is not a critical path and the interface that
trip_point_show() belongs to is problematic anyway (for instance, it
doesn't cover the case when the same cooling devices is associated
with multiple trip points).
This is a preliminary change and the affected code will be refined by
a series of subsequent modifications of thermal governors, the core and
the ACPI thermal driver.
The general functionality is not expected to be affected by this change.

thermal/core: Relocate the traces definition in thermal directory
The traces are exported but only local to the thermal core code. On
the other side, the traces take the thermal zone device structure as
argument, thus they have to rely on the exported thermal.h header
file. As we want to move the structure to the private thermal core
header, first we have to relocate those traces to the same place as
many drivers do.

thermal: Validate new state in cur_state_store()
In cur_state_store(), the new state of the cooling device is received
from user-space and is not validated by the thermal core but the same is
left for the individual drivers to take care of. Apart from duplicating
the code it leaves possibility for introducing bugs where a driver may
not do it right.
Lets make the thermal core check the new state itself and store the max
value in the cooling device structure.
