Reference: http://lkml.org/lkml/2009/6/4/240,
To fix the following build error:

drivers/net/lance.c: In function 'lance_probe1':
drivers/net/lance.c:575: error: implicit declaration of function 'isa_virt_to_bus'
drivers/net/lance.c: In function 'lance_rx':
drivers/net/lance.c:1197: error: implicit declaration of function 'isa_bus_to_virt'
make[2]: *** [drivers/net/lance.o] Error 1
make[1]: *** [drivers/net] Error 2
make: *** [drivers] Error 2

I would like to propose the following patch. The prototypes for the functions:
'isa_virt_to_bus' & 'isa_virt_to_bus' are existing for some archs like the
mips, x86, parisc, arm & alpha, but, is missing for powerpc. Is it safe to
introduce the following soultion for powerpc ? It fixes the build problem
i reported earlier.
