digilent_spi: add a driver for the iCEblink40 development board
This is driver that supports the Lattice iCE40 evaluation kits. On the
board is a SPI flash memory chip labeled ST 25P10VP.
Tested to work read/write/erase with "-p digilent_spi -c M25P10" or
with a patch that resets the part beforehands (in which case it gets
detected as a M25P10-A and is way faster due to paged writes).
