[PATCH] sparc64 cleanup cyclades.c

[Florian Lohoff <flo@rfc822.org>]

Hi,
attached a patch which cleanup the parts needed for sparc64. I am using
the driver currently. I can't verify if it breaks i386 or alpha which
seem to be the platforms now.

It changes the definition in cyclades.h to use the kernel fixed bit
defines therefor removes the need for the ifdef __alpha__. It then fixes
the irq beeing unsigned long not unsigned char also the error path
in the cyclom Y init. Need to free resources when aborting.

Against 2.4.18
