NFC: st21nfca: Auto-select core module

The core st21nca module is useless without the I2C access module.
So hide NFC_ST21NFCA and select it automatically if either
NFC_ST21NFCA_I2C is selected.

This avoids presenting NFC_ST21NFCA when NFC_ST21NFCA_I2C can't be
selected.

          STMicroelectronics ST21NFCA core driver. It implements the chipset
          HCI logic and hooks into the NFC kernel APIs. Physical layers will
