of _PTS is used by default).
s4_nonvs prevents the kernel from saving/restoring the
ACPI NVS memory during hibernation.
nonvs prevents the kernel from saving/restoring the
ACPI NVS memory during suspend/hibernation and resume.
sci_force_enable causes the kernel to set SCI_EN directly
on resume from S1/S3 (which is against the ACPI spec,
but some broken systems don't work without it).

Allows the configuration of the timer frequency. It is customary
to have the timer interrupt run at 1000 Hz or 100 Hz, but in the
case of low timer frequencies other values may be more suitable.
SH-Mobile systems using a 32768 Hz RCLK for clock events may want
to select a HZ value such as 128 that can evenly divide RCLK.
A HZ value that does not divide evenly may cause timer drift.
