PNP: define PNP-specific IORESOURCE_IO_* flags alongside IRQ, DMA, MEM

Browse source 
PNP previously defined PNP_PORT_FLAG_16BITADDR and PNP_PORT_FLAG_FIXED
in a private header file, but put those flags in struct resource.flags
fields.  Better to make them IORESOURCE_IO_* flags like the existing
IRQ, DMA, and MEM flags.
