staging: fwserial: delete the driver. 

In the years since it was added (2012), no one has stepped up to
maintain this properly and get it merged into the kernel tree.  So
remove it as it's obviously not being used.

If it is being used, we can easily revert this and take the time to get
it out of the staging tree.

	help

	  This enables TTY over IEEE 1394, providing high-speed serial

	  connectivity to cabled peers. This driver implements a

	  ad-hoc transport protocol and is currently limited to

	  Linux-to-Linux communication.



	  To compile this driver as a module, say M here:  the module will

	  be called firewire-serial.

	  Set this to the maximum number of serial ports you want the

	  firewire-serial driver to support.

	  Set this to the maximum number of serial ports each firewire

	  adapter supports. The actual number of serial ports registered

	  is set with the module parameter "ttys".

TODOs prior to this driver moving out of staging

------------------------------------------------

1. Implement retries for RCODE_BUSY, RCODE_NO_ACK and RCODE_SEND_ERROR

   - I/O is handled asynchronously which presents some issues when error

     conditions occur.

2. Implement _robust_ console on top of this. The existing prototype console

   driver is not ready for the big leagues yet.

3. Expose means of controlling attach/detach of peers via sysfs. Include

   GUID-to-port matching/whitelist/blacklist.



-- Issues with firewire stack --

1. This driver uses the same unregistered vendor id that the firewire core does

     (0xd00d1e). Perhaps this could be exposed as a define in

     firewire.h?
