soc/intel/apollolake: Enable logging for wake sources in S0ix
This change adds GSMI callback elog_gsmi_cb_platform_log_wake_source
to enable wake source logging from S0ix on APL/GLK. Additionally,
elog.c is added to smm stage.
BUG=b:79449585
TEST=Verified that S0ix entry/exit events are added to eventlog:
=========== Power button ============
59 | 2018-06-25 14:01:11 | S0ix Enter
60 | 2018-06-25 14:01:30 | S0ix Exit
61 | 2018-06-25 14:02:00 | Wake Source | Power Button | 0
=========== Lid open ================
62 | 2018-06-25 14:02:36 | S0ix Enter
63 | 2018-06-25 14:02:56 | S0ix Exit
64 | 2018-06-25 14:03:26 | Wake Source | GPE # | 15
65 | 2018-06-25 14:03:32 | Wake Source | GPE # | 65
66 | 2018-06-25 14:03:37 | EC Event | Lid Open
=========== Trackpad ================
67 | 2018-06-25 14:04:20 | S0ix Enter
68 | 2018-06-25 14:04:33 | S0ix Exit
69 | 2018-06-25 14:05:03 | Wake Source | GPE # | 15
70 | 2018-06-25 14:05:08 | Wake Source | GPE # | 66
