remove the obsolete xircom_tulip_cb driver

The xircom_tulip_cb driver has been replaced the xircom_cb driver, and
since it depended on BROKEN_ON_SMP it e.g. was no longer present in many
distribution kernels.

This patch therefore removes it.

-				Theory of Operation
-
-I. Board Compatibility
-
-This device driver was forked from the driver for the DECchip "Tulip",
-Digital's single-chip ethernet controllers for PCI.  It supports Xircom's
-almost-Tulip-compatible CBE-100 CardBus adapters.
-
-II. Board-specific settings
-
-PCI bus devices are configured by the system at boot time, so no jumpers
-need to be set on the board.  The system BIOS preferably should assign the
-PCI INTA signal to an otherwise unused system IRQ line.
-
-III. Driver operation
-
-IIIa. Ring buffers
-
-The Xircom can use either ring buffers or lists of Tx and Rx descriptors.
-This driver uses statically allocated rings of Rx and Tx descriptors, set at
-compile time by RX/TX_RING_SIZE.  This version of the driver allocates skbuffs
-for the Rx ring buffers at open() time and passes the skb->data field to the
-Xircom as receive data buffers.  When an incoming frame is less than
-RX_COPYBREAK bytes long, a fresh skbuff is allocated and the frame is
-copied to the new skbuff.  When the incoming frame is larger, the skbuff is
-passed directly up the protocol stack and replaced by a newly allocated
-skbuff.
-
-The RX_COPYBREAK value is chosen to trade-off the memory wasted by
-using a full-sized skbuff for small frames vs. the copying costs of larger
-frames.  For small frames the copying cost is negligible (esp. considering
-that we are pre-loading the cache with immediately useful header
-information).  For large frames the copying cost is non-trivial, and the
-larger copy might flush the cache of useful data.  A subtle aspect of this
-choice is that the Xircom only receives into longword aligned buffers, thus
-the IP header at offset 14 isn't longword aligned for further processing.
-Copied frames are put into the new skbuff at an offset of "+2", thus copying
-has the beneficial effect of aligning the IP header and preloading the
-cache.
-
-IIIC. Synchronization
-The driver runs as two independent, single-threaded flows of control.  One
-is the send-packet routine, which enforces single-threaded use by the
-dev->tbusy flag.  The other thread is the interrupt handler, which is single
-threaded by the hardware and other software.
-
-The send packet thread has partial control over the Tx ring and 'dev->tbusy'
-flag.  It sets the tbusy flag whenever it's queuing a Tx packet. If the next
-queue slot is empty, it clears the tbusy flag when finished otherwise it sets
-the 'tp->tx_full' flag.
-
-The interrupt handler has exclusive control over the Rx ring and records stats
-from the Tx ring.  (The Tx-done interrupt can't be selectively turned off, so
-we can't avoid the interrupt overhead by having the Tx routine reap the Tx
-stats.)	 After reaping the stats, it marks the queue entry as empty by setting
-the 'base' to zero.	 Iff the 'tp->tx_full' flag is set, it clears both the
-tx_full and tbusy flags.

- * To quote Arjan van de Ven:
- *   transceiver_voodoo() enables the external UTP plug thingy.
- *   it's called voodoo as I stole this code and cannot cross-reference
- *   it with the specification.
- * Actually it seems to go like this:
- * - GPIO2 enables the MII itself so we can talk to it. The MII gets reset
- *   so any prior MII settings are lost.
- * - GPIO0 enables the TP port so the MII can talk to the network.
- * - a software reset will reset both GPIO pins.
- * I also moved the software reset here, because doing it in xircom_up()
- * required enabling the GPIO pins each time, which reset the MII each time.
- * Thus we couldn't control the MII -- which sucks because we don't know
- * how to handle full-duplex modes so we *must* disable them.
