Sending the switch state change twice within the same frame is invalid
evdev protocol and only works if the client handles keys immediately as
well. Processing events immediately is incorrect, it forces a fake
order of events that does not exist on the device.

Recent versions of libinput changed to only process the device state and
SYN_REPORT time, so now the key event is lost.

The new notify_handler logic determining if autorelease should be used or
not is a bit awkward, and can result in more than one call to
sparse_keymap_report_event for the same event (scancode). The nesting
and long lines also made it difficult to read.

Simplify the logic by eliminating a level of nesting with a goto and
always calculate autorelease and val so we can make a single call to
sparse_keymap_report_event.

Suspend with shallow wakes is not a useful parameter since the phenomena
does not exist on deployed devices and is only a parameter of use during
device power-on phase. The field always reads zero. Additionally there
are other easier methods to detect it, e.g., if the S0ix counter
increments by more than one during suspend. Hence the field is superfluous
and can be removed.

This patch also slightly renames the S0ix total field for better
viewability.

Suspend stats are not reported consistently due to a limitation in the PMC
firmware. This limitation causes a delay in updating the s0ix counters and
residencies in the telemetry log upon s0ix exit. As a consequence, reading
these counters from the suspend-exit notifier may result in zero read.

This patch fixes this issue by cross-verifying the s0ix residencies from
the GCR TELEM registers in case the counters are not incremented in the
telemetry log after suspend.
