ft2232_spi.c: Implement spi_send_multicommand()

Every ftdi_write_data() call is quite time consuming as the ftdi-chips
seems to take always 2-3ms to respond. This leads to what the comment
already says: Minimize USB transfers by packing as many commands as
possible together. So I packed the WREN command together with the
following operation which can be program or erase operation.

This saves about 1 minute when programming a 128MBit Flash with my
config!
