[Impact]
To pass the energy star cert, the ASPM feature on RTL NIC should be enabled.

[Fix]
Enable the ASPM feature on all new Dell platforms, the family names are used on the new Dell platforms.
   Alienware
   Dell Laptops
   Dell Pro Laptops
   Dell Pro Max Laptops
   Dell Desktops
   Dell Pro Desktops
   Dell Pro Max Desktops
   Dell Pro Rugged Laptops
   Dell Pro Precision
   Dell Pro Essential
   Dell Pro Education
   XPS

[Test]
1. check the value of /sys/power/suspend_stats/total_hw_sleep
2. suspend and resume the system
3. the value of /sys/power/suspend_stats/total_hw_sleep increases

[Where problems could occur]
The listed family names are used in the new Dell platforms, so should not
impact the existing platforms. And Dell will push Realtek to fix the ASPM
issue found on RTL NIC.
