Remove all duplicate members from thermal_zone_device and directly
use the corresponding ones from struct thermal_zone_platform_params.
Please note that this also changes thermal_zone_device's type member
from char[THERMAL_NAME_LENGTH] to a const char *pointer, as the only
reason for this to not be const was that thermal_core was performing
a string copy operation, which is no more.
