Currently, PCHG can send a device event any time. When a signal is
sent to the host while it's attempting to suspend, suspend is delayed
by 10 seconds.
A solution is to make Powerd disable a corresponding PCHG event (i.e.
EC_DEVICE_EVENT_WLC) when it's notifying an upcoming suspend to other
processes.
This patch makes PCHG re-enable EC_DEVICE_EVENT_WLC after suspend is
complete.

Currently, device_set_events notifies the host even when the device
is masked by device_enabled_events. This patch makes it skip
notification for disabled devices.
This patch also makes device_event skip notification if it's already
set. Host reads & clears device_current_events atomically (by device
_get_and_clear_events). So, 1->1 transition means host has already
been notified but hasn't read it yet.

In order to report specific wake events from differernt devices
add a host command that allows setting device event mask, and
triggering a host event when that device event is set.
This is done as a separate command and mask because we are running
out of host events, and it takes over the unused thermal overload
event that was never used in EC or BIOS.
The first use case for this is platforms that have AP wake events
that go to the EC, for instance devices that use Deep S3 and have
a limited set of wake pins. (such as Eve)
This allows the AP to determine the exact wake source for an event
so it can be logged and acted on by the AP if necessary.
