[Cause of problem]
Logic of NFC HAL: after sending the commands, HAL will pull down NFC
GPIO0 and notify NFC chip that it can sleep after wait for 1 second.
If power key is pressed, AP will sleeps quickly, so that the 1 second timeout processing of NFC
HAL can not be executed, so the NFC chip cannot sleep.
But there is no issue if enter sleep is by screen auto time-out
[Solution]
In the NFc driver suspend call, check whether the hal has pulled down
NFC GPIO0. If not, prevent the system go to sleep 1 second.
[Side-effect]
None (The time to prevent go to sleep is 1 second, this can be ignored
in power consumption)
