Subject: [PATCH net-next v2 2/2] selftests: Add nci suite

From: Bongsu Jeon <bongsu.jeon@...sung.com>

This is the NCI test suite. It tests the NFC/NCI module using virtual NCI
device. Test cases consist of making the virtual NCI device on/off and
controlling the device's polling for NCI1.0 and NCI2.0 version.
