[RFC 1/6] pccard: remove bcm63xx socket driver

[Arnd Bergmann <arnd@kernel.org>]

From: Arnd Bergmann <arnd@arndb.de>

The bcm63xx pcmcia driver is the only nonstandard cardbus implementation,
everything else is handled by the yenta_socket driver. Upon a closer
look, this seems entirely unused, because:

 - There are two ports for bcm63xx in arch/mips, both of which
   support the bcm6358 hardware, but the newer one does not
   use this driver at all.

 - The only distro I could find for bcm63xx is OpenWRT, but they
   do not enable pcmcia support. However they have 130 patches,
   a lot of which are likely required to run anything at all.

 - The device list at https://deviwiki.com/wiki/Broadcom only
   lists machines using mini-PCI cards rather than PCMCIA or
   Cardbus devices.

 - The cardbus support is entirely made up to work with the
   kernel subsystem, but the hardware appears to just be a normal
   PCI host that should work fine after removing all the cardbus
   code.
