bcma: fix building without OF_IRQ
The bcma driver core can be built with or without DT support, but it fails to build when CONFIG_OF=y and CONFIG_OF_IRQ=n, which can happen on platforms that do not support IRQ domains. ERROR: "irq_create_of_mapping" [drivers/bcma/bcma.ko] undefined! ERROR: "of_irq_parse_raw" [drivers/bcma/bcma.ko] undefined! ERROR: "of_irq_parse_one" [drivers/bcma/bcma.ko] undefined! This adds another compile-time check for OF_IRQ, but also gets rid of now unneeded #ifdef checks: Using the simpler IS_ENABLED() check for OF_IRQ also covers the case of not having CONFIG_OF enabled. The check for CONFIG_OF_ADDRESS was added to allow building on architectures without OF_ADDRESS, but that has been addressed already in b1d06b60e90c ("of: Provide static inline function for of_translate_address if needed").
