ACPI / PM: Fix consistency check for power resources during resume
During system resume we check if there are power resources that have
been turned off by the BIOS, but our reference counters for them
are nonzero (they need to be turned on then). It turns out, however,
that we also need to check the opposite, i.e. if there are power
resources that have been turned on by the BIOS, but our reference
counters for them are zero (which means that no devices are going
to need them any time soon) and we should turn them off.
Make the power resources resume code do the additional check and
turn off the unused power resources as appropriate.
This change has been tested on HP nx6325.
