Srinivas Pandruvada 117e4e5bd9 thermal: intel: Avoid updating unsupported THERM_STATUS_CLEAR mask bits 
Some older processors don't allow BIT(13) and BIT(15) in the current
mask set by "THERM_STATUS_CLEAR_CORE_MASK". This results in:

unchecked MSR access error: WRMSR to 0x19c (tried to
write 0x000000000000aaa8) at rIP: 0xffffffff816f66a6
(throttle_active_work+0xa6/0x1d0)

To avoid unchecked MSR issues, check CPUID for each relevant feature and
use that information to set the supported feature bits only in the
"clear" mask for cores. Do the same for the analogous package mask set
by "THERM_STATUS_CLEAR_PKG_MASK".

Introduce functions thermal_intr_init_core_clear_mask() and
thermal_intr_init_pkg_clear_mask() to set core and package mask bits,
respectively. These functions are called during initialization.

Fixes: 6fe1e64b60 ("thermal: intel: Prevent accidental clearing of HFI status")
