Change subject: mb/asus/p2b{,-ls}: Get rid of power button device
......................................................................

Patch Set 2:

I looked at the vendor DSDT dump deeper. The flag in question is hardcoded in sb/intel/i82371eb/fadt.c yet matches the value in the vendor dump, yet it also has PWRB. I want to try controlling flag from a config option and flip it for boards that do have PWRB... then again it's just 3 boards in one family and they all have it. Another reason to not proceed with this change.
