[Impact]
ThinkPad 11e 3rd boot hang in systemd loading.

[Fix]
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.

Hi Kleber:

This SRU is missed, could you apply it to Bionic?

Regards,
Aaron

Hi Aaron,

Sorry about that. We failed to spot that "B/OEM" were meant for
bionic/linux and bionic/linux-oem.

I will add it to my list of patches to be applied for the next SRU
cycle. I will not apply it now though since we are still in the
beginning of this cycle, so better keep the branch clean in case we need
to re-spin.


Thanks,
Kleber
