From: Randy Dunlap <rdunlap at infradead.org>

Prevent drivers from building on PPC32 if they use isa_bus_to_virt(),
isa_virt_to_bus(), or isa_page_to_bus(), which are not available and
thus cause build errors.

../drivers/scsi/aha1542.c: In function 'aha1542_queuecommand':
../drivers/scsi/aha1542.c:461:30: error: implicit declaration of function 'isa_page_to_bus'; did you mean 'page_to_bus'? [-Werror=implicit-function-declaration]
