[PATCH 2/3] power: supply: axp20x_usb_power: Use power efficient workqueue for debounce

[Frank Lee]

From: Yangtao Li <fr...@allwinnertech.com>

The debounce timeout is generally quite long and the work not performance
critical so allow the scheduler to run the work anywhere rather than in
the normal per-CPU workqueue.
