Users may disable HWP in firmware, in which case intel_pstate wouldn't load unless the CPU model is explicitly supported.
Add TIGERLAKE to the list of CPUs that can register intel_pstate while not advertising the HWP capability. Without this change, an TIGERLAKE in no-HWP mode could only use the acpi_cpufreq frequency scaling driver.
