Only rpc uses disable_fiq, so make its use conditional on ARCH_RPC.

With this, entry-macro.S is no longer needed for platforms that
select MULTI_IRQ_HANDLER and the include of it can be conditional.

Using set_fiq_handler() in the rpc boot code we could get rid of 
disable_fiq entirely.

That's already being done here:
arch/arm/mach-rpc/dma.c:290:    set_fiq_handler(fiqhandler_start,
fiqhandler_length);

Can the macro just be deleted? Or a default handler needs to be setup
earlier?

That's the handler installed by the RPC DMA code.  Another one is needed 
by default for when that code is not active.
