Christophe Ricard a1269dd116 NFC: st-nci: Fix incorrect spi buffer size 
When sending data over SPI, the maximum expected length is the maximum
nci packet payload + data header size + the frame head room (1 for the
ndlc header) + the frame trail room (0).

Christophe Ricard 2bc4d4f8c8 nfc: st-nci: Add spi phy support for st21nfcb 
st21nfcb does support another phy than i2c: spi.
st21nfcc does not support spi as the spi ios are used
by the AMS RF booster.

st21nfcb is not following NCI NFC Forum recommendations for spi
but rely on ST prioritary protocol ndlc as for i2c.
