power: qcom: lock USB removal
During USB removal a lot of cleanup happens; votables are reset, flags
are cleared, etc. After the cleanup is finished there is a chance that
USB power supply consumers may set properties before getting the USB
removal notification. This can lead to many problems where ICL limits
are set based on the previous insertion, or APSD is disabled due to a
late setting of PD_ACTIVE.
Introduce a lock which prevents USB power supply consumers from setting
properties when USB has been removed. This lock will ensure that the
next insertion starts with a clean slate.
