soc/intel/{icl,tgl,jsl,ehl}: enable ACPI CPPC entries

Enable CPPC entries generation, needed for Intel SpeedShift.

This can be tested by checking sysfs in Linux:
$ grep . /sys/devices/system/cpu/cpu?/acpi_cppc/*perf

The output should look like this, while the values may differ:

  /sys/devices/system/cpu/cpu0/acpi_cppc/highest_perf:28
  /sys/devices/system/cpu/cpu0/acpi_cppc/lowest_nonlinear_perf:5
  /sys/devices/system/cpu/cpu0/acpi_cppc/lowest_perf:1
  /sys/devices/system/cpu/cpu0/acpi_cppc/nominal_perf:24
  /sys/devices/system/cpu/cpu1/acpi_cppc/highest_perf:28
  /sys/devices/system/cpu/cpu1/acpi_cppc/lowest_nonlinear_perf:5
  ...
