    platform/x86:intel/pmc: Disable ACPI PM Timer disabling on Sky and Kaby Lake

    There have been multiple reports that the ACPI PM Timer disabling is
    causing Sky and Kaby Lake systems to hang on all suspend (s2idle, s3,
    hibernate) methods.

    Remove the acpi_pm_tmr_ctl_offset and acpi_pm_tmr_disable_bit settings from
    spt_reg_map to disable the ACPI PM Timer disabling on Sky and Kaby Lake to
    fix the hang on suspend.
