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.
