ft2232_spi.c: release I/Os on shutdown

Resets FTDI I/O pins to high-Z (input) when shutting down. This allows
other devices to use the SPI bus without having to disconnect the
programmer.

This change will introduce a backward incompatibility in the case where
a user is relying on the state of FTDI outputs post-programming (eg. to
disallow another device from driving CS low).

However, there are likely more cases where releasing the SPI bus is the
correct thing to do.
