ft2232_spi.c: Implement spi_send_multicommand()

Every ftdi_write_data() call is quite time consuming when using flashrom
inside a virtual machine. This leads to what the comment already says:
Minimize USB transfers by packing as many commands as possible together.

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