Yueyao Zhu b9cd118403 USB: HAL: enable auto suspend for USB headsets ...

Adds a thread that handles add uevents of USB devices, and
enables auto suspend on that USB device (i.e. set power/control
to auto) if the device idProduct/idVendor is whitelisted.

The android kernel will already autosuspend audio devices,
however this enables autosuspend for the Google USB-C to
3.5mm adapter, which presents an HID-only interface when
no 3.5mm headset is connected.

Test: with the selinux and .rc changes for access permission
- MIR without headset: power/control set to auto
- MIR with headset: power/control set to auto
- regular mouse: power/control set to on
