passion: add qcom-post-boot service

note: caf uses init.svc.bootanim=stopped to run qcom-post-boot
however this causes a race condition between the post_boot script and
the BOOT_COMPLETE broadcast that evtoolbox uses to restore cpu settings.
In testing the post_boot script has always completed first but by less than
2 seconds and most by less than 1 second. I find that unacceptable.
Instead run post_boot on dev.bootcomplete=1 which is set at least 10
seconds before init.svc.bootanim=stopped and sys.boot_complete=1 (which
are set at the same time) Leaving plenty of time to ensure settings in
post_boot do not override user settings in evtoolbox.
