NFC: pn544: Switch to devm_acpi_dev_add_driver_gpios()
Switch to use managed variant of acpi_dev_add_driver_gpios() to simplify error path and fix potentially wrong assignment if ->probe() fails. Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
