Subject: [PATCH 09/19] thermal: sti: Remove obsolete STiH416 platform support.

STiH415/6 SoC support is being removed from the kernel.
This patch removes support from the thermal driver.
Also it updates the register defines and removes
the SoC and die prefix as neither of these are relevant
in the context of STiH407 based silicon (STiH415/6 were
dual die SoCs with an MPE die and SAS die).
