device/pci_early.c: Mixes up variants of a typedefs to 'u32'
Unfortunately coreboot has to deal with ROMCC's short comings which has lead to a little bit of confusion due to typedefs. Essentially, coreboot defines four typedefs: * 'typedef struct device * device_t' in ramstage not in SIMPLE_DEVICE mode * 'typedef u32 device_t' in romstage or when SIMPLE_DEVICE is defined * 'typedef u32 pnp_devfn_t' * 'typedef u32 pci_devfn_t' Some early functions make use of 'device_t' over 'pci_devfn_t' and since the C type-checker does not enforce typedefs to the same type 'u32' these are never noticed. Fix these so that 'device_t' does not conflict in romstage for later work. We later plan to have 'pnp_devfn_t' and 'pci_devfn_t' as the only variants of 'u32' and 'device_t' to be a struct pointer type exclusively.
