Negative temperature values can be set by thermal clients
to the TSENS driver. Having unsgined long type prevents
clients using the set_trip_temp() thermal api to set
negative temperature values. On msm-3.4 kernel this api
had support to set negative temperature. Change the type
to support the negative temperature.

In a heterogenous multiprocessor system, specifying the
'maxcpus' parameter on the kernel command line does not
provide sufficient control over which CPUs are brought
online at kernel boot time, since CPUs may have nonuniform
performance characteristics. Thus, we introduce a
'boot_cpus' command line argument, allowing the user to
explicitly specify the list of CPUs that shall be brought
online during kernel boot.
