[PATCH] virtio: uapi: avoid usage of libc types

["Thomas Weißschuh" <thomas.weissschuh@linutronix.de>]

Using libc types and headers from the UAPI headers is problematic as it
introduces a dependency on a full C toolchain.

On Linux 'unsigned long' works as a replacement for 'uintptr_t' and does
not depend on libc.
