power: supply: axp20x_usb_power: Use power efficient workqueue for debounce
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. Signed-off-by: Yangtao Li <frank@allwinnertech.com> Signed-off-by: Sebastian Reichel <sebastian.reichel@collabora.com>
