[PATCH] rapidio/switches: remove tsi500 driver

[Alexandre Bounine]

Remove the driver for Tsi500 Parallel RapidIO switch because this device is
not available for several years. Since the first introduction of Tsi500,
the parallel RapidIO interface was replaced by the serial RapidIO (sRIO)
and therefore there is no value in keeping this driver.
