ACPI / PM: Drop run_wake from struct acpi_device_wakeup_flags
The run_wake flag in struct acpi_device_wakeup_flags stores the
information on whether or not the device can generate wakeup
signals at run time, but in ACPI that really is equivalent to
being able to generate wakeup signals at all.
In fact, run_wake will always be set after successful executeion of
acpi_setup_gpe_for_wake(), but if that fails, the device will not be
able to use a wakeup GPE at all, so it won't be able to wake up the
systems from sleep states too. Hence, run_wake actually means that
the device is capable of triggering wakeup and so it is equivalent
to the valid flag.
For this reason, drop run_wake from struct acpi_device_wakeup_flags
and make sure that the valid flag is only set if
acpi_setup_gpe_for_wake() has been successful.
