angler: Accelerate boot by paralleling device enable
Some QCOM devices require sysfs to trigger boot/init which are blocking
the init process.
[ 7.453205] init: Command 'write /sys/kernel/boot_adsp/boot 1' action=post-fs-data (/init.angler.rc:166) returned 0 took 271.936ms.
This CL is to put those slow to start devices in a
separate service and wait for the service to be done later on.
Bug: 32712851
Test: On device
Change-Id: I675702a05b1e6b0b5e9b908a9b638a074fe92018
