ACPICA commit 129b75516fc49fe1fd6b8c5798f86c13854630b3

Stop nagging user about every Stall() that violates the spec

On my Dell XPS 15 7590 I get hundreds of these warnings after few hours of
uptime:

$ dmesg | grep "fix the firmware" | wc -l
261

I cannot fix the firmware and I doubt that Dell cares about 4 year old
laptop either
