WaitReady () -> TIMEOUT (when PN532 reader is selected)

[Pako2]

The PN532.cpp library contains the following snippet:

bool PN532::WaitReady() 
{
    uint16_t timer = 0;
    while (!IsReady()) 
    {
        if (timer >= PN532_TIMEOUT) 
        {
            Utils::Print("WaitReady() -> TIMEOUT\r\n");
            return false;
        }
        Utils::DelayMilli(10);
        timer += 10;        
    }
    return true;
}

As a result, the WaitReady () -> TIMEOUT message is very often listed in the serial monitor.
This is very annoying, and I propose the corresponding part (one single line) in the library to comment.

I have PN532 lying around somewhere, actually it need to be tested more.
