device/pci_early.c: Mixes up variants of a typedefs to 'u32'

Unfortantly 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 time exclusively.
