powerpc: Convert irq_domain_add_legacy_isa use to irq_domain_add_legacy
irq_domain_add_legacy_isa is a pain. It only exists for the benefit of two PPC-specific drivers, and creates an ugly dependency between asm/irq.h and linux/irqdomain.h Instead, let's convert these two drivers to irq_domain_add_legacy(), stop using NUM_ISA_INTERRUPTS by directly setting NR_IRQS_LEGACY. The dependency cannot be broken yet as there is a lot of PPC-related code that depends on it, but that's the first step towards it. A followup patch will remove irq_domain_add_legacy_isa. Signed-off-by: Marc Zyngier <maz@kernel.org>
