cs89x0: Move the driver into the Cirrus dir

The cs89x0 driver was initial placed in the apple/ when it
should have been placed in the cirrus/.  This resolves the
issue by moving the dirver and fixing up the respective
Kconfig(s) and Makefile(s).

Thanks to Sascha for reporting the issue.

-v2 Fix a config error that was introduced with v1 by removing
    the dependency on MACE for NET_VENDOR_APPLE.

+  Changelog:
+
+  Mike Cruse        : mcruse@cti-ltd.com
+                    : Changes for Linux 2.0 compatibility.
+                    : Added dev_id parameter in net_interrupt(),
+                    : request_irq() and free_irq(). Just NULL for now.
+
+  Mike Cruse        : Added MOD_INC_USE_COUNT and MOD_DEC_USE_COUNT macros
+                    : in net_open() and net_close() so kerneld would know
+                    : that the module is in use and wouldn't eject the
+                    : driver prematurely.
+
+  Mike Cruse        : Rewrote init_module() and cleanup_module using 8390.c
+                    : as an example. Disabled autoprobing in init_module(),
+                    : not a good thing to do to other devices while Linux
+                    : is running from all accounts.
+
+  Russ Nelson       : Jul 13 1998.  Added RxOnly DMA support.

+                    : email: ethernet@crystal.cirrus.com
+
+  Alan Cox          : Removed 1.2 support, added 2.1 extra counters.
+
+  Andrew Morton     : Kernel 2.3.48
+                    : Handle kmalloc() failures
+                    : Other resource allocation fixes
+                    : Add SMP locks
+                    : Integrate Russ Nelson's ALLOW_DMA functionality back in.
+                    : If ALLOW_DMA is true, make DMA runtime selectable
+                    : Folded in changes from Cirrus (Melody Lee
+                    : <klee@crystal.cirrus.com>)
+                    : Don't call netif_wake_queue() in net_send_packet()
+                    : Fixed an out-of-mem bug in dma_rx()
+                    : Updated Documentation/networking/cs89x0.txt
+
+  Andrew Morton     : Kernel 2.3.99-pre1

+                    : Replace '100' with HZ
+                    : Clean up a couple of skb API abuses
+                    : Added 'cs89x0_dma=N' kernel boot option
+                    : Correctly initialise lp->lock in non-module compile
+
+  Andrew Morton     : Kernel 2.3.99-pre4-1

+
+  Andrew Morton     : Kernel 2.4.0-test7-pre2

+
+  Andrew Morton     : Kernel 2.4.3-pre1
+                    : Request correct number of pages for DMA (Hugh Dickens)

+                    :  because unregister_netdev() calls get_stats.
+                    : Make `version[]' __initdata
