NFC: pn544: Auto-select core module 



As I understand it, the core nfc_pn544 module is useless without
either the I2C or the MEI access module. So hide NFC_PN544 and
select it automatically if either NFC_PN544_I2C or NFC_PN544_MEI is
selected.

This avoids presenting NFC_PN544 when neither NFC_PN544_I2C nor
NFC_PN544_MEI can be selected.
