arm64: wire in generic parport.h

The arm64 port doesn't provide a parport.h which causes a build failure with some configurations:

drivers/parport/parport_pc.c:67:25: fatal error: asm/parport.h: No such file or directory
#include <asm/parport.h>

This patch wires in the generic parport.h for arm64.

Can arm64 have a PC-style parport?

If not, you're better off disabling it in drivers/parport/Kconfig.

You will receive bonus points for introducing ARCH_MAY_HAVE_PC_PARPORT, cfr. ARCH_MAY_HAVE_PC_FDC.

In personal conversations with technical people, I call myself a hacker. But when I'm talking to journalists I just say "programmer" or something like that.

Good question. I'm not sure, but really doubt it.

Yes, good point. I'll work up a new patch. I can use some bonus points.

Okay, I have two versions of the patch. One which follows the PC_FDC patch and adds something like this to arch/<somearch>/Kconfig:

config ARCH_MAY_HAVE_PC_PARPORT
def_bool y

The other version adds:

config ARCH_MAY_HAVE_PC_PARPORT
bool

to arch/Kconfig (or maybe that should be in drivers/parport/Kconfig) so that the various arches just need to select it.

Is there any preference for one over the other?
