NFC: pn544: Auto-select core module

Browse source 
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.

NXP PN544 core driver.
This is a driver based on the HCI NFC kernel layers and
will thus not work with NXP libnfc library.
To compile this driver as a module, choose m here. The module will
be called pn544.
Say N if unsure.
