cpufreq: intel_pstate: Enable HWP IO boost for all servers 



The HWP IO boost results in slight improvements for IO performance on
both Ice Lake and Sapphire Rapid servers.

Currently there is a CPU model check for Skylake desktop and server along
with the ACPI PM profile for performance and enterprise servers to enable
IO boost.

Remove the CPU model check, so that all current server models enable HWP
IO boost by default.
