Patch for qspan_pci.c problem with GCC 2.95.2

Patch for qspan_pci.c problem with GCC 2.95.2

[Wohlgemuth, Jason]

Anyone trying to build in pci support to the kernel using GCC 2.95.2 may
find this patch helpful.

It seems that in the inline-assembly in qspan_pci.c the compiler doesn't
recognize that the first argument to the assembly may be modified.  This
resulted in a register getting trashed where it shouldn't have.  To fix the
problem I modified the in-line assembly to tell the compiler that this
register has been changed.

<               : "=r"(x) : "r"(addr) : "%0")

Well, that is an interesting way to do it.  We have been adding
temporary variables and using "+m" directives......

Thanks.
