NFC: pn533: Fix hardware busy loop when establishing the LLCP link
By using the standard setting for the regular pn533 dongles, we no longer wait for ever for an ATR_RES. Without this, a failing ATR_REQ will put the hardware into a busy loop, constantly waiting for an ATR_RES. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
