Michael Brown 92a9978b44 [spi] Add address-length autodetection to the SPI bit-bashing code 
Several SPI chips will respond to an SPI read command with a dummy
zero bit immediately prior to the first real data bit.  This can be
used to autodetect the address length, provided that the command
length and data length are already known, and that the MISO data line
is tied high.
