Remove drivers/net/auto_irq.c.

No more users of the autoirq_xxx() API existed, so this file is not
only unused, it isn't even listed in any makefiles.

-/* auto_irq.c: Auto-configure IRQ lines for linux. */
-/*
-    Written 1994 by Donald Becker.

-    The author may be reached as becker@scyld.com
-
-    This code is a general-purpose IRQ line detector for devices with
-    jumpered IRQ lines.  If you can make the device raise an IRQ (and
-    that IRQ line isn't already being used), these routines will tell
-    you what IRQ line it's using -- perfect for those oh-so-cool boot-time
-    device probes!
-
-    To use this, first call autoirq_setup(timeout). TIMEOUT is how many
-    'jiffies' (1/100 sec.) to detect other devices that have active IRQ lines,
-    and can usually be zero at boot.  'autoirq_setup()' returns the bit
-    vector of nominally-available IRQ lines (lines may be physically in-use,
-    but not yet registered to a device).
-    Next, set up your device to trigger an interrupt.
-    Finally call autoirq_report(TIMEOUT) to find out which IRQ line was
-    most recently active.  The TIMEOUT should usually be zero, but may
-    be set to the number of jiffies to wait for a slow device to raise an IRQ.
-
-    The idea of using the setup timeout to filter out bogus IRQs came from
-    the serial driver.
