PI3USB9281: Serialize mux setting and BC12 detection
Currently a PD task and a USB charger task can talk to PI3USB9281 to
update mux setting and to get BC12 information interleavingly. We
suspect this causes unreliable BC12 detection including detach detection.
This patch makes the usb_charger_set_switches API schedule a mux update
instead of changing the mux setting by itself wakes up a USB charger task.
A USB charger task solely handles BC12 detection and mux setting.

BUG=b/125176293
BRANCH=nami
TEST=Verify BC1.2 and PD charger can be detected correctly and
power_supply_info prints 'Discharging' when they're disconnected
on Syndra.
