tpm/st33zp24: Auto-select core module

Browse Source 
The core st33zp24 module is useless without either the I2C or the
SPI access module. So hide NFC_ST_NCI and select it automatically
if either TCG_TIS_ST33ZP24_I2C or TCG_TIS_ST33ZP24_SPI is selected.

This avoids presenting TCG_TIS_ST33ZP24 when neither TCG_TIS_ST33ZP24_I2C
nor TCG_TIS_ST33ZP24_SPI can be selected.
