net: atm: remove support for Fujitsu FireStream ATM devices

This driver received nothing but automated fixes (mostly spelling
and compiler warnings) since git era begun. Since it's using
virt_to_bus it's unlikely to be used on any modern platform.

-/* Small hardware gotcha:
-
-   The FS50 CAM (VP/VC match registers) always take the lowest channel
-   number that matches. This is not a problem.
-
-   However, they also ignore whether the channel is enabled or
-   not. This means that if you allocate channel 0 to 1.2 and then
-   channel 1 to 0.0, then disabeling channel 0 and writing 0 to the
-   match channel for channel 0 will "steal" the traffic from channel
-   1, even if you correctly disable channel 0.
-
-   Workaround: 
-
-   - When disabling channels, write an invalid VP/VC value to the
-   match register. (We use 0xffffffff, which in the worst case 
-   matches VP/VC = <maxVP>/<maxVC>, but I expect it not to match
-   anything as some "when not in use, program to 0" bits are now
-   programmed to 1...)
-
-   - Don't initialize the match registers to 0, as 0.0 is a valid
-   channel.

-/* Optimization hints and tips.
-
-   The FireStream chips are very capable of reducing the amount of
-   "interrupt-traffic" for the CPU. This driver requests an interrupt on EVERY
-   action. You could try to minimize this a bit. 
-
-   Besides that, the userspace->kernel copy and the PCI bus are the
-   performance limiting issues for this driver.
-
-   You could queue up a bunch of outgoing packets without telling the
-   FireStream. I'm not sure that's going to win you much though. The
-   Linux layer won't tell us in advance when it's not going to give us
-   any more packets in a while. So this is tricky to implement right without
-   introducing extra delays.
