SRU Justification:

[Impact]

When system profile is set to "Performance Per Watt (DAPC)" using BIOS setting, then install Ubuntu-22.04 and boot into OS then check the bootup time.

How reproducible: Always

Steps to Reproduce:

1. Set system profile as "Performance Per Watt (DAPC)" from BIOS setting
2. Install Ubuntu-22.04
3. Boot into OS
4. Check the bootup time

Expected results:
OS should boot normally and need to consume less bootup time

[Fix]

[Test Plan]

1. Set system profile as "Performance Per Watt (DAPC)" from BIOS setting
2. Install Ubuntu-22.04
3. Boot into OS
4. Check the bootup time

[Where problems could occur]

Regression risk: low to medium.
