msm8916: Give additional cores to background cpuset
* When a device with hundreds of apps is booted up, hundreds of
apps will spawn their BOOT_COMPLETED receivers which start
up their background initialization services. Since only one
core is allowed for these processes, the time for all these
services to complete is extremely long.
* To improve this, allow three cores for background processes,
keeping the fourth for idle wakeups. This ends up producing
a better thermal profile for the device as well, since the
small cores are not the aggressor on this SoC.
