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.

-                    : 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
