[PATCH] include: make the device_t types translation functions mutable

[Justus Winter]

Make the intran, outtran and destructor functions mutable using
preprocessor macros.  Make it possible to inject imports using the
DEVICE_IMPORTS macro.  This way, userspace servers can provide their
own translation functions.

* include/device/device_types.defs: Honor DEVICE_IMPORTS.
(device_t): Make the translation mutable using preprocessor macros.
