Default binderized implementation of android.hardware.nfc@1.0 



Provide a default binderized HAL implementation.  The implementation
uses android.hardware.nfc@1.0-impl.so, which in turn loads the
conventional HAL (nfc_nci.default.so).  If a device includes package
android.hardware.nfc@1.0-service, the device will automatically use the
binderized implementation of the NFC HAL.  If a device includes package
android.hardware.nfc@1.0-impl instead, it will use the default
implementation in hardware/interfaces/nfc/1.0/default.
