fix alpha ISA support
isa_bus_to_virt() is still needed in a few places (lance.c, at least). When
we switch the kernel to using -Werror-implicit-function-declaration, the
lack
of isa_bus_to_virt() breaks alpha allmodconfig builds.
Add isa_bus_to_virt() and deprecate the ezisting ISA APIs, though it might
be
better to define these functions as BUG(), since virt_to_bus/bus_to_virt
just
do wrong things on a number of machines.
