Setting the emulation temperature helps reproduce critical
temperature scenarios without risking the actual hardware at
extreme temperatures. Adding __ti_thermal_set_emul_temp as
the set_emul_temp hook.

Changes in v2:
* Rebased on top of:
git://git.kernel.org/pub/scm/linux/kernel/git/evalenti/linux-soc-thermal sysfs_locking
Tested on DRA7/DRA72 baords.
