[Qemu-devel] [PATCHv2] parallel: Allow to disable CONFIG_PARALLEL

[mrezanin@redhat.com]

From: Miroslav Rezanina <mrezanin@redhat.com>

Disabling CONFIG_PARALLEL cause build failure as commit 07dc788 factored
out initialization to parallel_hds_isa_init function in hw/char/parallel.c 
that is not build. 

Stub file is added to be able to disable CONFIG_PARALLEL. This file is used
in targets using parallel_hds_isa_init and provide empty definition of this
function.
