otPlatSpiSlaveEnable() function

Initialize the SPI slave interface. Note that SPI slave is not fully ready until a transaction is prepared using `otPlatSPISlavePrepareTransaction()`. If `otPlatSPISlavePrepareTransaction() is not called before the master begins a transaction, the resulting SPI transaction will send all `0xFF` bytes and discard all received bytes.
