superio: Use 'pnp_devfn_t' over 'device_t' in romstage component
The romstage component of Super I/O support is in fact written around passing a lower and upper half packed integer. We currently have two typedef's for this, 'device_t' and 'pnp_devfn_t'. We wish to make use of 'pnp_devfn_t' over 'device_t' as 'device_t' changes it's typedef in the ramstage context and so is really a conflicting definition. This helps solve problems down the road to having the 'real' 'device_t' definition usable in romstage later. This follows on from the rational given in: c2956e7 device/pci_early.c: Mixes up variants of a typedefs to 'u32' Change-Id: Ia9f238ebb944f9fe7b274621ee0c09a6de288a76 Signed-off-by: Edward O'Callaghan <eocallaghan@alterapraxis.com> Reviewed-on: http://review.coreboot.org/6231 Reviewed-by: Nico Huber <nico.h@gmx.de> Tested-by: build bot (Jenkins)
