ThinkPad 11e 3rd boot hang in systemd loading.

When boot case acpi_lpss_resume() get called without a
corresponding acpi_lpss_suspend() having been called.
Thus force setting the flag during boot.

[Test Case]
Tested on Thinkpad 11e 3rd.
Booting successfully.

[Regression Potential]
Low, upstream fix cherry-picked.

Cosmic already got this fix on 4.18.0-9.10.
