Hiding pointer types behind 'typedef's is usually not a great
idea at the best of times. Worse the typedef becomes an integer
at different stages in Coreboot. Let us refrain from doing this
at all.

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:

The romstage of Nuvoton Super I/O chips (but not Nuvoton BMC chips)
is identical, so the early_serial.c file can be moved under
nuvoton/common.
The Nuvoton BMC chip WPCM450 is however left untouched.

Find all the (ramstage) implementations of enter()/exit() functions
for the configuration state, register and call them through the new
struct pnp_mode_ops. As our standard PnP functions are aware of the
pnp_mode_ops, it's not necessary to call enter()/exit() around them
anymore.
Patch generated with the cocci below. It's not perfect. The movement
of the enter()/exit() calls is somehow fragile. So I checked the
remaining calls for sense, and changed some empty lines. Also a
duplicate insertion of pnp_conf_mode_ops had to be removed.

The current default implementation of pnp_enable() only disables devices
- if set so in the devicetree - but does not enable them. Enablement takes
place in pnp_enable_resources(). Yet, many PnP chips implement their own
version of pnp_enable() which also enables devices if set in the devicetree.
It's arguable, if enabling those devices makes sense, before they get
resources assigned. Maybe we can't write the resource registers if not,
who knows? The least we can do is providing a common implementation for
this behavior, and get rid of some code duplication.
Used the following cocci:
