power: supply: rk817: stop updating info in suspend

Browse Source 
The driver has a thread that checks the battery every 8 seconds. Stop
this thread during device suspend as while the device is suspended not
all values seem to be read correctly (such as battery voltage). The
resume function triggers the thread to start again.
