NFC: netlink: Add new netlink command NFC_CMD_ACTIVATE_TARGET

Some tag might get deactivated after some read or write tentative. This may happen for example with Mifare Ultralight C tag when trying to read the last 4 blocks (starting block 0x2c) configured as write only. NFC_CMD_ACTIVATE_TARGET will try to reselect the tag in order to detect if it got remove from the field or if it is still present.
