NFC: Read core reset notification

After chip has cold booted wait maximum of 50ms to
receive core reset notification.
Implement kernel ioctl to read whether core reset
notification has recieved before timeout.
Cold boot implementation of NFCC had a bug,
GPIO disable needs to be held high for atleast
100ms before switching it to low for a clean cold
boot.
