Subject: [patch 00/37] PNP resource_table cleanups, v2

This series of patches does some PNP housecleaning and
consolidation.
PNP currently uses a fixed-size table (pnp_resource_table)
to track the IO, MMIO, IRQ, and DMA resources used by a
device. Some motherboard devices have many resources, so
we've been plagued by table overflows and we've had to
drastically increase the table size, which wastes a lot
of memory.
The end goal is to replace that fixed-size table with something
more dynamic. These patches don't go that far, but they do make
pnp_resource_table private to the PNP core and centralize all
references to it in a small set of shared functions.
In addition, this series contains a number of related
cleanups, like centralized allocation of struct pnp_dev,
conversion to dev_printk when possible, removing many
PNP core internal functions from the public interface,
and alignment of the ISAPNP, PNPBIOS, and PNPACPI backends.
Changes between first post and v2:
- export pnp_get_resource()
- fix EISA ID conversion and make a common function for ISAPNP/PNPBIOS
- fix typos in pnp_check_{port,mem,etc} that made resource assign fail
- the following fixes should precede this series (they're in -mm already):
- parport_pc: wrap PNP probe code in CONFIG_PNP
- radio-cadet: wrap PNP probe code in CONFIG_PNP
- smsc-ircc2: wrap PNP probe code in CONFIG_PNP
- nsc-ircc: wrap PNP probe code in CONFIG_PNP
Thanks to Rene Herman for finding and fixing the EISA ID and resource
check bugs.
