SPI100k: Fix 8-bit and RX-only transfers
This change fixes 8-bit transfers and RX-only transfers. The
SPI100k framework requires minimum 16-bit words to be written, so 8-bit
transfers must be shited by 8 bits and sent out as a 16-bit word.
Additionally, receive-only transfers were failing due to the
perceived need to fill the TX buffer with something. This is in
fact not needed.
