[PATCH 1/2] spi: Add the SPI daisy chain support.

The implementation is transparent for the SPI devices and doesn't require their modifications. It is based on a virtual SPI device (spi-daisy_chain) and defines two required device tree properties ('spi-daisy-chain-len' and 'spi-daisy-chain-noop') and one optional ('spi-daisy-chain-bits_per_word').
