init: Enable adsprpcd instead of starting
This fixes the issue of the first boot on forceencrypt taking down
adsprpcd without starting it back up again.
init : processing action (vold.decrypt=trigger_shutdown_framework) from (/init.rc:715)
init : Service 'vendor.adsprpcd' (pid 592) received signal 9
"class main" brings it in sync with cdsprpcd, which is also in that
We can put it into "main" because the adsp and slpi devices will have
been and remain booted already when the
vold.decrypt=trigger_shutdown_framework prop triggers, no need to wait
until "late_start" to start the adsprpcd service back up again.
btw... TOLD YA! :)
