PNP: centralize resource option allocations 

This patch moves all the option allocations (pnp_mem, pnp_port, etc)
into the pnp_register_{mem,port,irq,dma}_resource() functions.  This
will make it easier to rework the option data structures.

The non-trivial part of this patch is the IRQ handling.  The backends
have to allocate a local pnp_irq_mask_t bitmap, populate it, and pass
a pointer to pnp_register_irq_resource().
