wpaul ebc77ad893 Fix support for Windows drivers that support both PCI and PCMCIA devices at
the same time.

Fix if_ndis_pccard.c so that it sets sc->ndis_dobj and sc->ndis_regvals.

Correct IMPORT_SFUNC() macros for the READ_PORT_BUFFER_xxx() routines,
which take 3 arguments, not 2.

This fixes it so that the Windows driver for my Cisco Aironet 340 PCMCIA
card works again. (Yes, I know the an(4) driver supports this card natively,
but it's the only PCMCIA device I have with a Windows XP driver.)

* that here, and let the build script create empty copies of
* device_if.h and bus_if.h to make the compiler happy.
