usb: host: u132-hcd: Delete driver

This driver got its last actual change in 2006 and is probably unused as
nowbody should use a cardbus to USB adapter any more.

If it were still used, the driver was in urgent need for maintainer
love. (Explicit kref handling, underdocumented locking, .remove() can
return errors ...)

Also the link in the (now removed) help text doesn't look actively
maintained. According to archive.org it forwarded to
http://www.copenhagen-hotel.net/ already back in 2018.

So don't waste more time on this driver and just delete it.

-	help
-	  The U132 adapter is a USB to CardBus adapter specifically designed
-	  for PC cards that contain an OHCI host controller. Typical PC cards
-	  are the Orange Mobile 3G Option GlobeTrotter Fusion card. The U132
-	  adapter will *NOT* work with PC cards that do not contain an OHCI
-	  controller.
-
-	  For those PC cards that contain multiple OHCI controllers only the
-	  first one is used.
-
-	  The driver consists of two modules, the "ftdi-elan" module is a
-	  USB client driver that interfaces to the FTDI chip within ELAN's
-	  USB-to-PCMCIA adapter, and this "u132-hcd" module is a USB host
-	  controller driver that talks to the OHCI controller within the
-	  CardBus cards that are inserted in the U132 adapter.
-
-	  This driver has been tested with a CardBus OHCI USB adapter, and
-	  worked with a USB PEN Drive inserted into the first USB port of
-	  the PCCARD. A rather pointless thing to do, but useful for testing.
-
-	  It is safe to say M here.
