Rafael J. Wysocki afa0ce0714 ACPI / EC: Restore polling during noirq suspend/resume phases 
[ Upstream commit 3cd091a773 ]

Commit 662591461c (ACPI / EC: Drop EC noirq hooks to fix a
regression) modified the ACPI EC driver so that it doesn't switch
over to busy polling mode during noirq stages of system suspend and
resume in an attempt to fix an issue resulting from that behavior.

However, that modification introduced a system resume regression on
Thinkpad X240, so make the EC driver switch over to the polling mode
during noirq stages of system suspend and resume again, which
effectively reverts the problematic commit.

Fixes: 662591461c (ACPI / EC: Drop EC noirq hooks to fix a regression)
