The binary representation for sensor 1 interrupt status was incorrectly
assembled, when compared to the full table given in the same comment
section. The conversion into hex was also incorrect, leading to
incorrect interrupt status bitmask for sensor 1. This would cause the
driver to incorrectly identify changes for sensor 1, when in fact it
was sensor 0, or a sensor access time out.

Fix the binary and hex representations in the comments, and the actual
bitmask macro.

Currently the TI thermal driver sets the sensor update interval based
on the polling of the thermal zone. In order to get the polling rate,
the code inspects the thermal zone device structure internals, thus
breaking the self-encapsulation of the thermal framework core
framework.

On the other side, we see the common polling rates set in the device
tree for the platforms using this driver are 500 or 1000 ms.

Setting the polling rate to 250 ms would be far enough to cover the
combination we found in the device tree.

Instead of accessing the thermal zone device structure polling rate,
let's use a common update interval of 250 ms for the driver.

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.

The thermal framework provides an API to get the trip related to a
trip point id. We want to consolidate the generic trip points code,
thus preventing the different drivers to deal with the trip points
after they registered them.

The set_trip_temp ops will be changed regarding the above changes but
first we need to rework a bit the different implementation in the
drivers.

The goal is to prevent using the trip id but use a trip point passed
as parameter which will contain all the needed information.

As we don't have the trip point passed as parameter yet, we get the
trip point using the generic trip thermal framewrok APIs and use it to
take exactly the same decisions.

The difference with this change and the previous code is from where we
get the thermal trip point (which is the same).

No functional change intended.

Merge Intel thermal driver fixes for 6.3-rc5:

 - Fix handling of two recently added module parameters in the Intel
   powerclamp thermal driver (David Arcari).

 - Fix one more deadlock in the int340x thermal driver (Srinivas
   Pandruvada).

* thermal-intel-fixes:
  thermal: intel: powerclamp: Fix cpumask and max_idle module parameters
  thermal: intel: int340x: processor_thermal: Fix additional deadlock

When cpumask is specified as a module parameter the value is
overwritten by the module init routine.  This can easily be fixed
by checking to see if the mask has already been allocated in the
init routine.

When max_idle is specified as a module parameter a panic will occur.
The problem is that the idle_injection_cpu_mask is not allocated until
the module init routine executes. This can easily be fixed by allocating
the cpumask if it's not already allocated.
