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.

As I understand it, the core nfcmrvl module is useless without
either the USB or the UART access module. So hide NFC_MRVL and select
it automatically if either NFC_MRVL_USB or NFC_MRVL_UART is selected.
This avoids presenting NFC_MRVL when neither NFC_MRVL_USB nor
NFC_MRVL_UART can be selected.

It also avoids building the core driver when no physical layer has been
selected.
All 3 patches applied to nfc-next, thanks.
Cheers,
