NFC: pn544: Separate the core code and the i2c one into different modules As we may need to support other physical layers, we can avoid linking the core part into each and every pn544 module. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

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.

NXP PN544 core driver.
This is a driver based on the HCI NFC kernel layers and
will thus not work with NXP libnfc library.

This module adds support for the NXP pn544 i2c interface.
Select this if your platform is using the i2c bus.
If you choose to build a module, it'll be called pn544_i2c.

This module adds support for the mei interface of adapters using
NXP pn544 chipsets. Select this if your pn544 chipset
is handled by Intel's Management Engine Interface on your platform.
If you choose to build a module, it'll be called pn544_mei.
Say N if unsure.
