chipset_enable.c: Add Ice Lake U to known and tested systems

Intel Ice Lake systems use an 495 Series Chipset
that behaves compatible to pch300 chips but chip names
are undocumented at this point.

This change was tested in read/write/erase on the Razer
Blade Stealth (late 2019) with intel 1065G7 CPU and
"Ice Lake U Premium PCH".
