Olliver Schinagl e946f7a97a drivers: pn532_i2c: Errata on i2c timing 
The datasheet is wrong for the pn532_i2c. After having constant issues
with the device failing to respond on the bus and after contacting NXP
about this, it turns out 1.3 ms is too tight. The official timing spec
is unknown for now, but we tested 4 and 5 ms without problems. Thus we
have choosen 5 ms as a safe delay.
