/*
* Fix 300-series RTC Bug
* For 300-series only. If you can't force enable Legacy RTC in BIOS GUI.
* macOS does yet not support AWAC, so we have to force enable RTC. Do not use RTC ACPI patch.
*
* The Time and Alarm device provides an alternative to the real time clock (RTC), which is defined as a fixed feature hardware device.
* The wake timers allow the system to transition from the S3 (or optionally S4/S5) state to S0 state after a time period elapses.
* In comparison with the Real Time Clock (RTC) Alarm, the Time and Alarm device provides a larger scale of flexibility in the operation of the wake timers,
* and allows the implementation of the time source to be abstracted from the OSPM.
